/trigger ChangeOrigin

Inspired by @sylenthuntress's original ChangeOrigin datapack. This version is non-configurable but has a 3 hour trial with infinite changes when the player first joins the server.

Features:

• The trial and changes reset when a player changes username.
• A player has two origin changes that they can access with /trigger ChangeOrigin. These are infinite for the first 3 hours.
• When someone first joins the server, they are notified of their trial and the fact that they can do this.
• When the 3 hour trial ends, they are notified and have a button to get one last free change, to prevent players from getting stuck on an origin they don't like when the trial ends.

If you want to change anything, leave a message on the Discord and I'll tell you what needs to be edited in the data.
