allows you to build belts that connect directly into Nether Portals.
The belt will visually extend into the portal frame, and any items traveling along it will be transferred to a matching portal on the other side.
The items load chunks shortly after having entered the portal just like items dropped by a dispenser.
To achieve seamless tranportation, the portals should be of the same size and orientation so that the belts can be connected to the corresponding portal block on both sides.
