Request: Add support for MIDI 1.0 UMP to MIDI 2.0 UMP Protocol upscaling

[Psychlist1972]

You currently have the MIDI 2 UMP <-> MIDI 1 UMP transform. This is a request for the opposite.

In practice, all MIDI 2.0 devices should be able to handle MIDI 1.0 messages, but that isn't a hard requirement in the spec.

If, during discovery, a device declares support for MIDI 2.0 protocol, but does not declare support for MIDI 1.0 protocol, we want to be able to upscale MIDI 1.0 messages sent to the endpoint.
