Framework for Regional Trades

This implements much of the stuff Martha wants for the regional forms.
- Alola forms have trades; version exclusives moved to Pewter
- Galar forms will be on the S.S. Anne to promote returning
- Regional form evos will be on the S.S. Anne possibly? Maybe something else.

Also contains a similar-to-LGPE trade quote. Extremely compressed quotes.
