Any chance of adding `game_area_collision` support for Pokemon Yellow?

Unless I'm doing something wrong, it seems like the `GameWrapperPokemonGen1.game_area_collision` method doesn't work for the case of Pokemon Yellow, despite the fact that it has the same map as Blue and Red. Would it be possible to fix this?

Start at GameWrapperPokemonGen1.game_area_collision and compare how it handles Pokemon Yellow with its behavior for Blue and Red. Confirm the map collision behavior and verify that the method works for Yellow without breaking the existing cases.
