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
Will need to verify if Beast Balls can be used on other Pokémon, and if generic Poké Balls can be used on Ultra Beasts. We'll see when GO Fest Berlin starts.
* 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.
struct implementing interface is boxed when passed to method that accepts interface (not generic method).
Removes IDexLevel (no other inheritors but EvoCriteria) and uses the primitive the data is stored (array, not IReadOnlyList) for slightly better perf.

* Draft checks for encounter slot mastery
* Check encounter mastery flags
* Add moves for LA static encounters that don't follow learnset
* Add moves on crossover LA static encounters
* add alpha moveset population method
Now generates and applies moves as the game does
Updates some handling of other methods to use Span
* Show better message for bad mastery init flags
* Insert descending if candidates have same level
Level 78 Yanmega:
- [01] [10] Quick Attack
- [06] [15] Gust
- [11] [20] Silver Wind
- [18] [28] Hypnosis
- [25] [35] Air Slash
- [34] [45] Ancient Power
- [43] [54] Crunch
- [43] [54] Bug Buzz
Yields:
AlphaMove
Crunch*
Bug Buzz*
Ancient Power
* Descending order due to iteration

* 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.
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.
* 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.
