Parse maps Warp data

[kemenaran]

For now maps have their header and blocks data disassembled, but not their warp data.

From the LALE hacking notes:

Warps
Each screen can have one warp

5-Byte Warps

• First byte = Area Type (E tells it to be a warp, 2 = area type)
  • 00 = overworld
  • 01 = dungeons A
  • 02 = dungeons B
• Second byte = Dungeon map (00 = Level 1, 01 = Level 2, etc)
• Third byte = Dest Room (Must be in map of the dest dungeon)
• Fourth byte = X (Tile x, extra X)
• Fifth byte = Y (Add 10, starts at header)

These Warp data can probably be parsed and disassembled to a readable ASM format (by a script similar to tools/generate_map_data.py).

Note by @Xkeeper0:

map_parser.py currently treats any FE as an end-of-room marker, but this appears in warp data for a few rooms (namely Overworld13 and OverworldE3, maybe others)

This means room objects need to be properly parsed to parse warp data.
