[BUG]: midi.exe monitor does not decode Discovery messages (and other minor message decoding issues)

[Psychlist1972]

Also midi endpoint monitor shows only 2 words for a MIDI 1 UMP device like the NI S49

Finally, it would be helpful for messages like pitchbend, nrpn/rpn if the full 14 bit value was shown, not just discrete MSB/LSB
