Adjust project structure and add poetry

[SimonBrandner]

This PR adjusts the project structure for better readability. It also adds poetry for better dependency management

Hi Simon, thanks for the pull request!

I have no experience with poetry, but it looks like a good idea. However, I have the following problem:

I try to run

> poetry install

and get the error

Package operations: 1 install, 0 updates, 0 removals

  • Installing pycairo (1.24.0): Failed

  TypeError

  Can't instantiate abstract class IsolatedEnv with abstract methods make_extra_environ, python_executable

I actually have pycairo installed on my system, so the program runs flawlessly without the poetry sandbox. Do you have an idea on how to fix that?

Best, M

Argh, I haven't seen that before, no, not really sure how to help you there...

@michibo, we you able to figure out what's going on? I'd like to move this forward, though I am not sure how to help on your side to be frank... We could do this without poetry but I think it helps with dep management quite a bit...
