Describe the solution you'd like

With the announcement and finally, the release, of Pokémon Legends Z-A, one of the many tasks on our list should be to introduce compatibility for its save files as soon as we can. While it being released [as of now] 4 days ago will be an issue, once we see reverse engineering pick up in the community for it's save files, we can start working towards implementing the compat for it.

I'm working on adding the new mega evolution data. But yeah save file support will come once PKHeX adds support and I can shamelessly use their code as a reference

Tasks:

• New mega evolution data
• New mega evolution sprites
• New items
• New move
• Latin American Spanish
• Met locations
• Game of Origin
• Save file compatibility
