* 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.
Removes a lot of the offset-by-1 indexing, notably in the `GameStrings.GetLocationName` method which shifted everything 1. BDSP files we dumped don't replicate this off by 1, and I don't see a reason to maintain this off-by-1 for prior games since it's unnecessary quirks to maintain.
Zero indexed ftw.
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.
O(n) for speed & memory usage, as good as we can get.
Modified method is now less dumb. Array Copy doesn't have to worry about same-array overlapping src/dest regions
