feat: Create Cairo2Midi transpiler

[raphaelDkhn]

We need a Cairo2Midi transpiler, to convert Koji MIDI back to Midi.

You can take inspiration to Midi2Cairo converter.
You should probably use mido lib, to create the MIDI object.

@raphaelDkhn Wow I worked on a MIDI project in OCaml earlier (basically implementing RTPMidi protocol over ethernet). It's so cool to find another MIDI project!!
Can I please take this one too? I'll have a blast working on this one :D

Sounds great @AryanGodara 🔥

def midi_to_cairo_struct(midi_file, output_file):

Just to be sure, I have to now implement a function like this one right?

def cairo_struct_to_midi(...)

Yes :) based on the MIDI Cairo struct
