Extract common abstract class for shared logic
Clean up property/field/method ordering to be consistent and logical (roughly: attributes, constructors, state management, retrievable values, static methods)
Apply default language OT name
Use underscores for enum for ToString replacing with spaces
Don't flag empty-OT as SK2; Stadium0/1 use the "TRAINER" as rental, but leave it blank for SK2.
Don't set any terminators for an OT string if the string is empty; just wipe the buffer.
Readonly slots
Things could be expanded on to use interfaces and wrappers for a "SlotReference" and properties for readonly.
But that's kinda unnecessary
Introducing a new PKM format: SK2
Split ICaughtData2 off of PK2 so it can be shared with SK2 when type-checks occur
Add conversion for PK2<->SK2
Split the split-buffer handling for GBPKM to GBPKML (what a name), so that I can reuse shared accessor logic for SK2.
