Datapack with /Trigger command for resizing

Allows players on a server to change sizes within a balanced range without needing access to commands.

It is in my opinion an awful implementation, but it does work. No guarantee on this not creating a lot of lag for what it does.

It works like this for the size of 0.67.

/trigger resize_067

It works like this for the size of 1.33.

/trigger resize_133
