Requires Fabric Language Kotlin and Fabric API.
This is mostly a recreation of the Lapis Portals Bukkit plugin, which I used to play 5 or 6 years ago.
Build the portal structure out of lapis, and close the door to teleports you to another portal that's on the same 'channel'.
The channel of a portal is determined by what's in its storage (only caring about item ids, not NBT or count)
No Lapis Portals code was used or referenced in making this mod.
