- Add `pokemon_species.evolves_from_species_id` (and a corresponding
entry in `pokemon_evolution`) to new species which evolve from galarian
forms (Obstagoon, Perrserker, Cursola, Sirfetch'd, Mr. Rime, Runerigus),
which were incorrectly listed as base pokemon.
- Add missing evolution methods for a few more non-default forms (Alolan
Sandshrew, Alolan Vulpix, Alolan Meowth, Galarian Slowpoke, Galarian
Darumaka, Dusk Lycanroc)
This also adds two new evolution triggers for Sirfetch'd and Runerigus
The step counts we had weren't even good estimates. To hatch an egg
uninterrupted takes (counter + 1) * 255 steps in gen IV; what we had
was counter * 256.
Phione and Manaphy have different counters, as do Croagunk and Toxicroak
for some reason, so they're associated with individual Pokémon now,
rather than entire evolution chains. Double-checked with Pearl,
Platinum, and SoulSilver; there were no differences between the three,
aside from the alternate forms introduced in Platinum.
