Subject: [PATCH] Smooth teleport config

Removed since Leaf 1.21.4

This abuses some of how Minecraft works and attempts to teleport a player to another world without
triggering typical respawn packets. All of natural state of chunk resends, entity adds/removes, etc still
happen but the visual "refresh" of a world change is hidden. Depending on the destination location/world,
this can act as a "smooth teleport" to a world if the new world is very similar looking to the old one.
