Fill command

The server /fill command is a way to add many blocks to a world quickly
There is however a "flaw" with the command
If you try to initialize a world with the fill command, there is a good chance you will get this error:

   That position is not loaded

The issue is that the server fill command only works on world blocks that are currently loaded.
This behavior will not work for us, so I created a "fill" command that spawns blocks in a loop instead:

You add the type of block, location to start and the x,y,z offsets which indicate how width, height, and long you want to fill
