Due to how the game generates the Pokémon data, the first two (or three) RNG calls are used to set the 32-bit `EncryptionConstant` and `PID`. With 2x 32-bit and 1x 64-bit values, we can algorithmically reverse the movement & manipulation of bits to recover the initial seed. Notably, certain bits of the initial state are not captured by our first two (or three) outputs, so we must brute-force guess at the initial state, and verify the RNG's output yields the expected values.
**With the ability for real-time Xoroshiro128+ seed reversal, we can now validate RNG correlations for SW/SH raid encounters natively within the program.** For now, the legality fail error message is extremely vague and any validated seed won't be "remembered" for the Legality Parse like other RNG methods. These seeds are 64bit, while every other "remembered" `PID/IV` seed-info is 32-bit.

We implement simple state machine iterators to iterate through every split type encounter array, and more finely control the path we iterate through. And, by using generics, we can have the compiler generate optimized code to avoid virtual calls.
In addition to this, we shift away from the big-5 encounter types and not inherit from an abstract class. This allows for creating a PK* of a specific type and directly writing properties (no virtual calls). Plus we can now fine-tune each encounter type to call specific code, and not have to worry about future game encounter types bothering the generation routines.
GO imports that are created with their PK7 and PB7 movesets can bleed from their initial moves.
Example: Muk-Alola level 20 with Minimize can bleed into SV at level 20 (below the normal learn at level 21).
Like move validation, evolutions are the earliest thing we wish to traverse when determining what encounters may have originated the current Pokémon. To determine the permitted species-form-levels a Pokémon could originate with, we must devolve a Pokémon by traveling down-generation to origin. Once we have an encounter, we can then evolve it to the current species, traversing upwards from origin to the current format.
Runtime/jit repoints these to the dll rather than heap if we're Little Endian (always, otherwise will allocate like before).
Eliminates quite a few static constructors, so even faster startup. Items later.
Updates from net46->net7, dropping support for mono in favor of using the latest runtime (along with the performance/API improvements). Releases will be posted as 64bit only for now.
Refactors a good amount of internal API methods to be more performant and more customizable for future updates & fixes.
Adds functionality for Batch Editor commands to `>`, `<` and <=/>=
TID/SID properties renamed to TID16/SID16 for clarity; other properties exposed for Gen7 / display variants.
Main window has a new layout to account for DPI scaling (8 point grid)
Fixed: Tatsugiri and Paldean Tauros now output Showdown form names as Showdown expects
Changed: Gen9 species now interact based on the confirmed National Dex IDs (closes#3724)
Fixed: Pokedex set all no longer clears species with unavailable non-base forms (closes#3720)
Changed: Hyper Training suggestions now apply for level 50 in SV. (closes#3714)
Fixed: B2/W2 hatched egg met locations exclusive to specific versions are now explicitly checked (closes#3691)
Added: Properties for ribbon/mark count (closes#3659)
Fixed: Traded SV eggs are now checked correctly (closes#3692)
Adds support for Scarlet & Violet.

In this pull request I've changed a ton of method signatures to reflect the more-narrow types of Species, Move# and Form; additionally, I've narrowed other large collections that stored lists of species / permitted values, and reworked them to be more performant with the latest API spaghetti that PKHeX provides. Roamer met locations, usually in a range of [max-min]<64, can be quickly checked using a bitflag operation on a UInt64. Other collections (like "Is this from Colosseum or XD") were eliminated -- shadow state is not transferred COLO<->XD, so having a Shadow ID or matching the met location from a gift/wild encounter is a sufficient check for "originated in XD".
Rewrites a good amount of legality APIs pertaining to:
* Legal moves that can be learned
* Evolution chains & cross-generation paths
* Memory validation with forgotten moves
In generation 8, there are 3 separate contexts an entity can exist in: SW/SH, BD/SP, and LA. Not every entity can cross between them, and not every entity from generation 7 can exist in generation 8 (Gogoat, etc). By creating class models representing the restrictions to cross each boundary, we are able to better track and validate data.
The old implementation of validating moves was greedy: it would iterate for all generations and evolutions, and build a full list of every move that can be learned, storing it on the heap. Now, we check one game group at a time to see if the entity can learn a move that hasn't yet been validated. End result is an algorithm that requires 0 allocation, and a smaller/quicker search space.
The old implementation of storing move parses was inefficient; for each move that was parsed, a new object is created and adjusted depending on the parse. Now, move parse results are `struct` and store the move parse contiguously in memory. End result is faster parsing and 0 memory allocation.
* `PersonalTable` objects have been improved with new API methods to check if a species+form can exist in the game.
* `IEncounterTemplate` objects have been improved to indicate the `EntityContext` they originate in (similar to `Generation`).
* Some APIs have been extended to accept `Span<T>` instead of Array/IEnumerable
Many years ago, PKX used to be a >4,000 line bloated file, which spun off multiple classes like CommonEdits and most of the early non-GUI PKM related logic. Now, it's just a stub to source the latest generation & personal table.
Separate files = more concise info, and more room to grow to do more advanced things.
Makes the IsPresent methods public (no longer internal).
Instantiating from template now follows group seed -> spawn 1 correlation, including alpha move.
Differentiates static encounters that don't follow the ow8a correlation, scrambles EC to disassociate.
Adds rand64 to get initial seeds
Set correct level range to match slotSeed; not respecting the slot roll being valid, but whatever.
ddc6f414df caused it to be `<=` instead of `<`, but maybe the underlying issue was fixed a different way since all tests still pass with this reversion.
* Reuses move parse result objects for each encounter parsed in a LegalityCheck attempt, instead of creating a new object.
* Ensures the objects are never-null, and makes cleanup easier.
Slightly adjusts some other parts of the moveset validation to reduce allocations.
Adds structures to read/write saved spawner data such as seeds, counts.
Adds generator and validator to emulate the FixInitSpec builder used by the game logic
Similar to SW/SH raids, validating these in-process is not feasible due to the number crunching required.
This does not handle the encounter slot call or the follow-up level range call. Just the inner FixInitSpec ctor & fill.
level is calc'd:
randFloat(sum) -> slot float
rand.Next() -> gen_seed (for all the details)
rand.NextInt(delta) +min -> level

Existing `get`/`set` logic is flawed in that it doesn't work on Big Endian operating systems, and it allocates heap objects when it doesn't need to.
`System.Buffers.Binary.BinaryPrimitives` in the `System.Memory` NuGet package provides both Little Endian and Big Endian methods to read and write data; all the `get`/`set` operations have been reworked to use this new API. This removes the need for PKHeX's manual `BigEndian` class, as all functions are already covered by the BinaryPrimitives API.
The `StringConverter` has now been rewritten to accept a Span to read from & write to, no longer requiring a temporary StringBuilder.
Other Fixes included:
- The Super Training UI for Gen6 has been reworked according to the latest block structure additions.
- Cloning a Stadium2 Save File now works correctly (opening from the Folder browser list).
- Checksum & Sanity properties removed from parent PKM class, and is now implemented via interface.
