Fixed issues with marker-spawned entities spawning too high or too low
Cartographers shouldnt spam / crash the server
Vision Gui will now close when studio closes
Fixed several commands that use context
Iris commands will now use "default" as the default iris world type, which now uses the config.json's default world type instead of assuming "overworld"
Removed headless generation, it is no longer a fast option for 1.18+ as the biome palettes dramatically slow down region filling speeds. At this point either using the iris pregenerator or something like chunky will both run at roughly the same speed.
