+Usage: python3 free_space.py [BANK=none] [pokecrystal.map]

+Calculate the free space in the ROM or its individual banks.

+The BANK argument allows printing free space in one, all, or none of the ROM's banks.
+Valid arguments are numbers (in decimal "42" or hexadecimal "0x2A"), "all" or "none".
+If not specified, defaults to "none".
