Automate construction of pokemon-related arrays

[bbepis]

There are two arrays in code that are currently tied to having a 1-1 relationship with individual pokemon, however are currently hardcoded in source:

• sTeachableMoves, which dictates which moves can be taught to which pokemon from move tutors
• Unk_ov113_02260D90, which is somewhat related to overworld footprint data (amity square?)

These ideally should be dynamically generated from data.json files for each species
