Library to parse both mapfiles and elfs

[AngheloAlf]

Try to parse from either or both to get as much symbol information possible.

Probably use mapfile_parser for mapfiles.

Also consider parsing debug sections to get extra symbol information. For example mdebug parsing: https://github.com/zeldaret/oot/blob/0c6c112cb9a3a8f12d0f4865743853857bbdc88e/sym_info.py
