New *Required Biome* stat that makes items only work in certain biomes. Case and space insensitive

Adding 'mountains' will make this work on every biome variant that has 'mountains' in its name (Like modified_gravelly_mountains).

Use the '!' prefix to blacklist biomes instead. '!forest' will make the item not work in any forest variant.
