* Heavily rewrites the `PKH` abstractions.
* Uses HOME's core-side classes as the transfer middlemen instead of direct A->B transfers.
* Revises logic to account for most of HOME's quirks (scale/height copying, safe refuge PLA)
Future revisions hinge on better handling of evotree (need better metadata about existing as specific evolutions in each game).

* 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.
