Add support for upgrading/degrading pouches (Regular <-> Colossal)

[Infinitay]

In the current state, if a user goes back to regular pouches from a colossal pouch: should those regular pouches have had their state initialized before and the plugin was never reset, then those regular pouches will retain their state when they should have been reset. The same applies vice-versa.

This is a pain to test without beta worlds or the ability to spawn in items into the game.

Possible implementation:

• If at any point a regular pouch is added to the inventory: reset the colossal pouch
• If at any point a colossal pouch is added to the inventory: reset all regular pouches
