Add scripts to find unit, program IP address

[mikepurvis]

SOPAS is able to do these things using UDP broadcast tricks. For example, the following is three instances of the UDP payload to "discover" LIDARs on the local network segments:

10:00:00:08:ff:ff:ff:ff:ff:ff:41:2e:b5:ee:01:00:0a:d3:37:05:ff:ff:ff:00

10:00:00:08:ff:ff:ff:ff:ff:ff:3b:1e:a9:a0:01:00:0a:d3:37:05:ff:ff:ff:00

10:00:00:08:ff:ff:ff:ff:ff:ff:36:27:b9:d6:01:00:0a:d3:37:05:ff:ff:ff:00

                                                IP          netmask

This message is transmitted to 255.255.255.255, with a src and dest port of 30718. Full PCAP of these interactions coming soon.

You… you mean I might not need to use SOPAS anymore?

Eventually yes— can't commit to a timeline, unfortunately.

@jeff-o has furnished a wireshark capture of the SOPAS tool finding a unit and programming its IP address. This can be found here:
