Core/Maps: Parse MFBO adt chunk to properly handle height where player counts as falling under the map

Browse Source 
* This fixes the height at which player is instantly killed when falling from The Frozen Throne
* Set PLAYER_FLAGS_IS_OUT_OF_BOUNDS on players under the map to enable release spirit button while still falling

Note: Extracting new maps is required
