* 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.
Yay abstractions to hide away the quirks.
BDSP traded eggs set HT_Friendship and the CurrentHandler flag, but the HatchCounter is always the OT_Friendship value.
Trades always receive BaseFriendship, instead of a hardcoded 50. Necessary to not hardcode because it's immutable for eggs.
Clicking the hatch counter label now sets it to the legal minimum hatch counter (best), and control clicking sets it to the max (worst). Check the encounter template for the true maximum.
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.
