Allow ignored egg moves for v1.0 unpatched games

Browse Source 
They didn't reference the TamagoWazaIgnore table until v1.1 lmao

mimic BDSP's index fetching and just grab the array of eggmoves directly to avoid the abstraction method's overhead

set evotree back to private because don't need direct access anymore
