Rusemi - USB Serial to CoreMIDI CLI converter

Hi everybody!

Rusemi is an open-source command line utility written in Rust and designed to convert MIDI-formatted messages coming from USB serial ports to virtual MIDI ports via CoreMIDI (and the other way around).
I created it to help me debug MIDI communication for hardware projects based on Arduino, STM32 and other microcontrollers without having to depend on custom bootloaders / firmwares.

It can be used as a replacement for Hairless MIDI which, unfortunately, hasn’t been updated to 64-bit.

While this may be a very niche utility, I figured it’d be a good idea to share it here in case someone else is looking for a similar tool.
