add support for openwrt

[zunder1990]

most devices that run openwrt dont have the storage or ram to run a full DWCC node.

So here is the working idea for this.
Have a full node that will act as a controller for lite nodes. The full node will ssh into the lite node a run tcpdump over ssh with saving the pcap local to the full node. The full node will open a 2nd ssh connection to the lite node to change the wifi channel.
