Custom Player Heads

New config options:

• debug mode to make my life easier
• option to disable the inclusion of the Floodgate prefix in the head names
• option to enable a "/getskull" command to get bedrock & java player heads.
• option to change the permission level necessary to use the command

Fixes:

• actually cache the player's skin file; atleast until the server restarts

/getskull:

• an optional command - you can set the permission level in the config, default is 2. 0 would be everyone, 4 is OP's only. Or disable the command entirely!
• /getskull [javaname]: gets you any java players' skull
• /getskull bedrock [bedrockplayer]: gets you a skull from a Bedrock player. Due to how this works, they absolutely NEED to have joined ANY geyser+floodgate server recently. Otherwise, i can't get the skin data from the Geyser API
• autocomplete (java only) for both bedrock, and java players!
• spelling for [bedrockplayers] does not matter - it is not case sensitive. You can, but don't have to include a prefix - you will get the skull with the name you have inputted

NOTE: due to Geyser not translating fabric command suggestion packets properly on Geyser-Standalone, you might get an error similar to

[20:30:14.927 nioEventLoopGroup-4-1/WARN] Downstream packet error! Value 48 has no mapping for key class com.github.steveice10.mc.protocol.data.game.command.CommandParser.

I can't do anything about this - if you do not like it, either filter the logs with a log filter plugin, OR disable the command in the config. This shouldn't affect you if you're running fabric behind Velocity.
