Install error

[pkoevesdi]

To be able to install everything from requirements.txt, I had to
apt-get install libcairo2 libcairo2-dev libgirepository1.0-dev python3-dbus
on a RPi 3B+.
Maybe this could be integrated into readme.md?

Also some packages made problems, which I could solve by changing

• typed-ast==1.4.3 to typed-ast>=1.4.3
• PyGObject==3.38.0 to PyGObject>=3.38.0
• dbus-python==1.2.16 to pydbus (I read it here)

in requirements.txt. I don't know, if this is a good fix, but it made the project work for me.

Quite many dependencies for this project. Are they really all neccesary?

By the way, I was not able to get it running in a python environment, I had to install and run globally.
