Create: Portal Logistics

It 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.
