Update Dumper

[hdjwis]

A motorized winch that pulls the storage box up and back to dump. This will likely have 2 limit switches as well for the stowed and dumping positions of the dump box

the storage bin can only be pulled back when the auger is completely stowed (both actuators fully retracted)

Need to update node to use proximity switches, when mechanical/electrical decide
