Added disabled-worlds option in config.yml. if you add a world name there, hats will be disabled in that world.
Added /hat visibility command. this allows you to toggle visibility of hats.
Added /hat selfhatvisibility command. this allows you to only toggle visibility of your own hat.
Fixed NPC hat feature.
We have instead added /hats spawn command which will spawn a hat on top of your head that will stay in the same location and not follow you. You can use this to spawn hats on top of NPCs heads. To remove the hat simply stand in 1 block distance to the hat and type /hats despawn
Major fix:
i have made hat's rotation more smooth. now it wont look like its teleporting. (it was never teleporting).
Added support for 1.21
