lack of interfaces and default interface implementations is killing me :)
Split GameData so we can interact with changed data structures a little less weird; PLA Learnsets are too incompatible for direct edits with existing abstractions.
Thanks @sora10pls for double checking some editors, and @Lusamine for some field identification.
Closes#115 -- tested the pokedex after randomization and it no longer crashes when randomizing+saving with the latest code in this pull request.
Adds:
* Shop editor (SWSH + LGPE)
* Move editor
* Item editor
* Symbol (Overworld Pokemon) Behavior editor
* Default Rental team editor
pkNX will now prompt the user to select a version before opening the wild editor, should no ExeFS data exist to determine which game is currently loaded.
Previous implementation did not work correctly for LGPE. If someone wishes to merge the wild encounter buttons again, make sure it works for all games before submitting a pull request. Also fixes LGPE wild editor using small sprites.
Closes#110
