* 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.
* Providing pkm/sav files via command line (dragging files onto exe / associated file launched) will more intelligently source a partner sav/pkm object if not provided.
* Gen1/2 mainline save files now indicate if they are VC era or GB era (legality implications) in the program title bar.
* Fixes loading VC era save backups not being recognized as VC era (`.bak` extension hides `.dat`)
* Export BAK moved to the SAV tab, which allows Export main to be deleted and Export SAV to be used as the single-click for exporting saves. `CTRL-E` is still the hotkey.
