Extend the Box System to hold more mons

[SaltContainer]

The vanilla game has 40 boxes, and that can Just Barely sqeueze every species from gen 1-8 plus msot of the forms, however, that leaves no room for dupes, shinies, and no room for the mons that have Tons of forms like Alcremie, Vivillon, Floette line etc etc

as well as no room for gen 9 either

So need to add to the amount of boxes, maybe 20 or so? or just double it to 80

This might require some RomFS stuff for the UI, since there's some things that are hardcoded there. Or maybe just dupe some of the existing stuff kind of like how the new settings are done
