Remove map errors near Hyrule Castle depths

[jordanbtucker]

There have been two inaccessible map areas visible since the game's release, however those areas have been removed from the map in v1.2.0.

Pre v1.2.0

v1.2.0

Thanks for finding this. :)
This would require remaking the full map and then regenerating the map tiles.

I've got some map gen work done in #82 , it's not perfect but would do the trick if 1.2 map files haven't been renamed too much.
