Undertale 2 Effect Sprites & Spell Icons

• readds mod support for a few mods that somehow got deleted in the last 2 updates
• adds support for mutant mobs, mutants buff, brewin + chewin, battletowers, vint delight, cold sweat, projectile damage attribute, obscureapi, buzzier bees, potion of bees, gigeresque

some textures will look weird without the moremcmeta mod, due to animation stuff
