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.
Sure it's nice to cache a valid array, but the amount of logic was small enough that it can be done with 10 lines of code rather than at the end of each verification method.
Reduces parameter passing & removes 1 field from the info object, as relearn suggestions are only done rarely after legality checking.
Allows for a simpler api surface (pkm, encounter) rather than a bigger object reference
