Port PureRGB AI

Short tests showed positive results. Revert if it fucks up anything.

PureRGB enhances Gen 1 AI in various ways, fixing notorious glitches and making it not do completely stupid things. I would use shin pokered's, but it may be too difficult for unfamiliar players, and has a bunch of outdated markers I'd have to spruce up.

Relevant changes:
- Burn effect calls have been replaced with Fire Blast's effect, replicating the burn spread use-case of Fire Blast
- Teleport references removed because pureRGB uses a unique version
- Any straggler references to effects not used in pureRGB
- Mist properly referred to as we only have one move that provides stat drop immunity.

Updated the sprite gallery too!!
