                        1.17 - Brigadier
Now that we have mappings on paper, we should move our commands to brigadier.
This is mostly complete, with the following issues:
- I had to remove our custom flag argument, so we need another way to handle trailing flags in command arguments.
 - Our command is registered as /minecraft:otg.
 - /otg map biomes and /otg map terrain produce a black image in 0 seconds.
