This is all the Pokémon data except moves and held items, which need to be
ripped separately for all Pokémon.
Note that Cosplay Pikachu and friends are technically in the Undiscovered egg
group, but egg groups are a property of PokemonSpecies so i can't represent
that here.
English names only for now. Still need to add names for old default forms,
e.g., Hoopa Confined.
Still need to regenerate the order columns.
Looks like pokemon_form_generations and pokemon_game_indices haven't been kept
up to date, so i guess i'll have to update those too.
Updates #141.
