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
New current handler verifier settings flag GO => LGPE transfers. Unlike GO => HOME, these transfers use your LGPE OT info, so it's legal to have no HT and have the current handler be OT

* 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.
* Make EvolutionCriteria struct
8 bytes per object instead of 26
Unify LevelMin/LevelMax to match EncounterTemplate
bubble up precise array type for better iteration
* Inline queue operations, less allocation
* Inline some logic
* Update EvolutionChain.cs
* Improve clarity on duplicate move check
* Search reverse
For a dual stage chain, finds it first iteration rather than second.
* 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.
Have `Shiny.Random` be `0`, so we can skip init on this field for EncounterStatic. Plus makes it a little less brittle for future expansion if shiny qualities change.
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.
The Encounter verifier method rarely rejects as our inner encounter matching methods are all-or-nothing. Don't bother keeping references for this bloat.
Ran the unit tests and nothing hit this logic.
Old: when an encounter is found, we copied the contents of the list into our analysis list.
Since we stop when we find a suitable encounter, the old list is useless. By sharing the same list, there's no consequence. Reduces allocation by ~56B each analysis object!
Simplification reduces the amount of method calls by 1
Looks like Mr. Rime case wasn't being handled, so I rewrote it. Better performance, less complexity. No need to double-reference the moves.
Cache a single Valid evolution result; every parse can reuse that object.
- Settings now stored as json next to exe
- Settings now exposes all legality checking setttings that can be changed
- Slot hovering now can play cries in MGDB/PKMDB/etc, not just the main boxes.
- Enhanced hover text for mystery gifts and encounters that have movesets
- Show recently loaded save files in ctrl-f browser
- Toggle auto-load savefile setting to be none/detect-latest/last-loaded
- Custom extensions & extra backup paths can now be configured directly in the json settings
- Settings editor now uses propertygrid & tabs.
GameStrings: 10% of strings are unique; just mark everything. Stop a little early so we don't process the empty & (trade) string.
LearnsetReader: All empty entries are length==0; malformed should throw an exception (never).
EggMoves: Compute ptr inside the array fetch loop; don't use linq.
EggMoves & string shaves off 80ms of startup time according to profiling; some could be attributed to warm-up but yay more efficient.
AltForm & Form & Forme => Form
GenNumber & Generation => Generation
Extract out SpeciesForm interface, and re-add IGeneration
For those using PKHeX as a dependency, this should be a pretty straightforward manual replacement... GenNumber and AltForm should be quick find-replace`s.
