Description of the new feature / enhancement

I hope that we can support previewing midi file and other symbolic music formats (such as musicxml, vocaloid .vsqx, etc.) in peek as piano roll.

I'm going to implement this feature by myself.

Scenario when this would be used?

For musicians, when organizing projects or handling collaboration files, we often need to quickly identify what’s inside a MIDI file. One‑click preview in File Explorer with Peek—without waiting for any heavy professional software (DAWs or musescore) to launch—can reduce this task from tens of seconds to under a second.
