Built-in multi-world support!

[Iapetus-11]

• PyMine should have built-in support for multiple worlds (aside from the default overworld, nether, and end)
• Perhaps there would be a set of commands allowing for the easy management of the worlds.

Reason

• Multi-world plugins tend to be jank or hard to use, PyMine having built in multi-world support would be an excellent addition.

world "groups" - collections of worlds that are linked together (think inventorys/playerdata) to allow for mutiple overworlds, nethers and ends natural portals

It would be great if this worked across multiple physical Instances like bungeecord

Or allow this to be used with bungee cord.
