Script to hide fill types in silos without fill quantity V1.0

This script hides all fill types that have no quantity in the silo when unloading from the silo into a trailer or device. All entered fill types can still be stored in the silo. Only those with a quantity of 0 are hidden when unloading. This also depends on the trailer/device. However, to use it, there must be at least 1 fill type in the silo.
