Start rtpMIDI if it is not running; it also restarts itself if it crashes

- Hold MIDI on "LIGHT PC MIDI GONE" starts the rtpMIDI service, then its tray
  app, only if they are not running (a restart drops every session).
- The Lighting PC's rtpMIDI service now has Windows recovery actions
  (restart after 5 s, 5 s, 30 s); windows-setup.ps1 sets the same.
- coremidi.disconnect_peer (Disconnect in Audio MIDI Setup), used to test the
  alarms: all six links dropped and came back (four by themselves, two by
  the hold).
- Audio MIDI Setup need not be open: quitting it on NA Ingest left the
  session connected.
