MIDI key: every network MIDI peer must come over the wired network

The Macs are also on Wi-Fi and the Dante networks, and Bonjour lists each MIDI session once per
network. ProdDash's Vista Cues module had Tracks and Companion set to their Wi-Fi addresses, so
lighting MIDI rode Wi-Fi. A midi_wired check now names any peer, in NA Ingest's session or the
other Macs', whose address is outside the wired network (10.1.0.0/16 at NA).
