25b217c53d Skip first iteration check of stop condition
Can unroll the loop, but would look more ugly :)
JIT will probably do it for us.

Fix <= to < for IVs
Inline temp var (start is unused after assigning to low)

2a190dd6b3 Improve LCRNG seed reversal speed ~50x
Big thanks to Parzival from the RNG discord community for chiseling the LCRNG search space down to the best performing implementation possible.

50x? Down from O(2^8) -> O(2^3) is 32x, but we no longer need to access two heap arrays (262KB no longer needed!). Everything can be calculated tightly with the stack.

f641f3eab2/RNG/LCG_Reversal.py (L31)

Rainbow tables is the only faster implementation. However, nobody is gonna hog many GB of RAM for O(1) reversals. This is ~O(2^3), down from O(2^8). Much better than the days of O(2^16)!

Refactor RNG advance/reverse methods (#3579)
The new LCRNG/GCRNG/ARNG classes are static, rather than singletons. Allows them to be inlined much better.

File scoped namespaces (#3529)
[Language Reference](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-10.0/file-scoped-namespaces)

Updates all the files, one less level of indentation.

Some small changes were made to API surfaces, renaming `PKM pkm` -> `PKM pk`, and `LegalityAnalysis.pkm` -> `LegalityAnalysis.Entity`

ShowdownSet: Lessen allocation
MoveTutor: Remove boxing by calling the generic method instead of object method
Xoro8b: Add more xmldoc, use positive constant instead of inverse negative for parity
StadiumUtil: Use built-in endianness reversal methods

Add logic for PLA wild RNG correlation (#3443)
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

Refactoring: Span-based value writes and method signatures (#3361)
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.

cc8ac7a4f1 Remove unnecessary warning suppression
fixed dat .editorconfig in vs22
Catching general exceptions is okay because this program handles user modified data that can potentially be corrupt.

Update 21.11.19 - Brilliant Diamond & Shining Pearl (#3289)
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.
