Fix Python packaging for Python 3.12 (#79)

* Translate setup.py to pyproject.toml

* Introduce PEP518 by using Poetry as package manager
* Introduce PEP402-ish package structure
* Remove requirements.txt and setup.py
* Update Dockerfile and Docs for new packaging method

* Bump dependencies, remove six

six is no longer necessary as of docker-py 5.0.1 (see docker/docker-py#2863)
