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.

Relocate checksum adders to Checksums class, improve performance by eliminating slice calls
Improve HOME sharing for GO8 and IMoveset encounters: actually sanity check GO8, and skip other non-PK7/PB7 cases.
Move enum -> ushort instead of int
Redo handling of HOME Volt Tackle (disallow on SWSH Cap Pikachu)
Pass spans instead of strings to use span methods
Reset encounter filters on early abort
* Heavily rewrites the `PKH` abstractions.
* Uses HOME's core-side classes as the transfer middlemen instead of direct A->B transfers.
* Revises logic to account for most of HOME's quirks (scale/height copying, safe refuge PLA)
Future revisions hinge on better handling of evotree (need better metadata about existing as specific evolutions in each game).

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.

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

apparently Japanese XD uses 32bit instead of 64bit, different struct size. Seems the same as the memo size being different for japanese XD too.
Since we're now using Config, apply the correct CurrentRegion/OriginalRegion values when setting a pk* to sav.
* Revises legality checks to account for traveling between the three game islands (PLA/BDSP/SWSH)
* Adds conversion mechanisms between the three formats, as well as flexible conversion options to backfill missing data (thanks GameFreak/ILCA for opting for lossy conversion instead of updating the games).
* Adds API abstractions for HOME data storage format (EKH/PKH format 1, aka EH1/PH1).
* Revises some APIs for better usage:
- `PKM` now exposes a `Context` to indicate the isolation context for legality purposes.
- Some method signatures have changed to accept `Context` or `GameVersion` instead of a vague `int` for Generation.
- Evolution History is now tracked in the Legality parse for specific contexts, rather than only per generation.
Big thanks to @SciresM @sora10pls @Lusamine @architdate @ReignOfComputer for testing and contributing code / test cases. Can't add co-authors from the PR menu :(
Builds will fail because azure pipelines not yet updated with net6.
Change Ability array to IReadOnlyList, add method to check ability index in personal data
Suppress some message warnings
Change EvolutionChain short-circuit for VC to jump from gen6 directly down to gen2. There aren't any notradeback 1 situations, so a notradeback1 will always start with g=1, so no need for the other if-continue.
Simplify pk5 conversion
* Rework gen1 slot loading
Slot templates are precomputed from ROM data and just loaded straight in, with tight coupling to the encounter area (grouped by slot types).
* Revise fuzzy met check for underleveled wild evos
Example: Level 23 poliwhirl in RBY as a level 50 poliwhirl, will assume the chain is 25-50 for poliwhirl (as poliwag evolves at 25). Instead of revising the origin chain, just ignore the evo min level in the comparison.
Previous commit fixed it for gen1.
* Rework gen2-4 slot loading
Gen4 not finished, Type Encounter data and some edge encounters not recognizing yet...
* Add feebas slots for old/good encounters
* Begin moving properties
Great news! Gen5-7 need to be de-dumbed like Gen1-4.
Then I can remove the bang (!) on the Area accessor and ensure that it's never null!
* Split off XD pokespot slot encounter table type
* Set area in constructor
* Deduplicate g3 roaming encounters
* Deduplicate xd encounter locations (rebattle)
Only difference is met location; no need to create 500 extra encounter objects. A simple contains check is ok (rarely in gen3 format).
* Make all slots have a readonly reference to their parent area
* Minor clean
* Remove "Safari" slot type flag
Can be determined via other means (generation-location), allows us to reduce the size of SlotType member to a byte
Output of slot binaries didn't preserve the Safari flag anyway.
* Update SlotType.cs
* Handle type encounters correctly
* Merge safari area into regular xy area
* Merge dexnav accessor logic
* fix some logic so that tests pass again
rearrange g5 dw init to be done outside of static constructor (initializer instead)
PIDGenerator: friend safari slots now generate with required flawless IV count
* Add cianwood tentacool gift encounter
* Remove unnecessary abstractions
Fake area just returned a slot; since Slots have a non-null reference to the area, we can just return the slot and use the API to grab a list of possible slots for the chain.
Increase restrictiveness of location/type get-set operations
* Minor tweaks, pass parameters
DexNav observed state isn't necessary to use, only need to see if it's possible to dexnav. Now that we have metadata for slots, we can.
* Remove unused legality tables
