Pokemon Transfer factual data references

The converter and UI are new MPL-2.0 code. No PKHeX code or binaries are bundled.
Compact factual species, stat, PP, species-index and character-encoding tables
were extracted for compatibility from the following primary references:

https://github.com/pret/pokeemerald (species_info.h, species_names.h, battle_moves.h,
  constants/species.h, constants/moves.h, constants/pokemon.h, charmap.txt)
https://github.com/pret/pokered (data/pokemon/base_stats, data/pokemon/dex_order.asm)
https://github.com/pret/pokecrystal (constants/charmap.asm)

Save layouts were independently implemented after consulting the pret projects
and PKHeX's published save-format documentation/source. PKHeX is not a runtime
dependency. Pokemon names and game names belong to their respective owners.
This custom conversion does not claim to reproduce an official Nintendo transfer.
