Cargo drones don't display route info

Also something that should be pretty easy, just a reminder to myself. In theory it should be pretty easy to change this, though I don't know what happens if you make the pickup/dropoff area larger than the game lets you.

Notes to self about this:
Need to figure out how to make 8 numbers fit into 5 slots, or make more slots. (Pickup corner 1, pickup corner 2, dropoff corner 1, ... (x, y))
Cargo ports are placed on the map, but the cargo drone is what stores these values. Need to iterate through cargo drones to find which port goes with which drone, and efficiently or it could take some time to load
