Implement missing console commands (if they're still needed):

• /otg biome (-s, -d, -f)
• /otg biome -m
• /otg biomes
• /otg lookup
• /otg exportbo4data
• /otg blocks
• /otg entities
• /otg particles
• /otg structure
• /otg export
• /otg spawn

Make a separate ticket when working on individual commands.

/otg data should replace the need for biomes, blocks, entities, particles

Still to-do:

• /otg biome
• /otg lookup
• /otg exportbo4data
• /otg structure
• /otg export
• /otg spawn

The wiki has a list of commands for 1.12.2: https://github.com/PG85/OpenTerrainGenerator/wiki/GUI-and-Commands

/otg spawn works for bo4's as well now, should be done. Otg export has a separate issue.
