midifile: add support for UMP

Browse source 
Add a type to the events, which can be MIDI1 or UMP.

Add debug functions for UMP messages.

midifile only supports saving MIDI1 format files for now. It will convert
to MIDI1 when asked to write an UMP message.

In pw-cat, convert the MIDI1 messages to UMP before sending into the
graph.
