uci: Implement UCI packet dissector

Implement the dissector for Ultra-wideband controller
interface packets, based on the protocol description
on the FiRa consortium website:
  https://groups.firaconsortium.org/wg/members/document/1679

The dissector recognizes packets with PCAP identifier 293,
or TCP packets on port 7000 (default).
