Add get_biome_id(biome_name) callback
It returns the index used in mg->biomemap for a given biome name. The biomemap is useless without this unless you re-register all existing biomes, which could cause problems for anyone else trying to use biomemap. With this, you can quickly create a lookup table of ids and names.
