This format won't be supported cleanly, so let's just try to allow language detection to work as best as it can without storing metadata in the SK2 bytes.
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.
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.
