This adds support for the Observer's MWOCP67 PSU, based on Murata's draft of acan-157.pdf.
Not yet supported:

  • Firmware update commands. There's a ticket for that.
  • A blackbox feature that looks complicated to use. The old MWOCP68 has a (somewhat different) blackbox feature that we're not using, so I'm guessing there's not much demand for this one either.

This will close #28
