Added RehearsalMark to midi export as Markers

Resolves: Add Marker meta events to MIDI export and Exporting Rehearsal Markers to MIDI files

I want to export Rehearsal Marks to Midi Markers.
I export my sheetmusic as midi into a DAW, where Midi meta events such as Markers are supported.
Usually the sheetmusic contains Rehearsal Marks and I want the same structure to appear in my DAW.

This PR only adds export functionality. Import of Midi Markers to Rehearsal Marks is still missing.

I did not unit test the implementation but it works for the few examples I have on my machine.
I was also able to check it with python:

from miditoolkit import MidiFile
midFile = r"path\to\midi.mid"
midi_obj = MidiFile(midFile)

print(midi_obj)

ticks per beat: 480
max tick: 226561
tempo changes: 1
time sig: 1
key sig: 13
markers: 182
lyrics: True
instruments: 13

print(midi_obj.markers)

[Marker(text="A", time=7680), Marker(text="B", time=53760), ...

Regarding the Codestyle check:

In installed uncrustify on my windows machine and ran it in git bash. However other than complaining about an outdated configuration it did not throw any erros for the mentioned file.

EDIT: had to install 0.73 of uncrustify via choco install uncrustify --version=0.73

[cbjeukendrup]

The problem is that you need specifically version 0.73 of Uncrustify. (We decided to pin the version at some point, because every Uncrustify update required changes to the code, which was quite inconvenient in combination with the fact that updates are rolled out gradually over GitHub Actions runners, so you never know in advance whether you're going to get a the new or old version.)

Don't use merge commits, but rebase (and force push):
git pull --rebase upstream master; git push --force

Sorry, my vscode git integration keeps doing those in the background. I believe I have removed most of the unnecessary merge commits
