pusher.lua:
Simple node for push/pull operation of StackItems from chests or other
inventory/server nodes to tubes or other inventory/server nodes.
The Pusher is based on the class NodeStates and supports the following messages:
- topic = "on", payload = nil
- topic = "off", payload = nil
- topic = "state", payload = nil,
response is "running", "stopped", "standby", "blocked", or "not supported"
