Python 3.11 support

[Turakar]

When installing with pip using pip install git+https://github.com/automl/DeepCAVE.git I get ERROR: Package 'deepcave' requires a different Python: 3.11.7 not in '<3.10,>=3.9'. I am not familiar with the DeepCAVE code and dependencies, but usually this should be as easy as increasing the compatible version and testing that everything still works.

As we currently have one dependency (pyrfr, which requires swig) that causes problems when testing with Python 3.11, we have not included it in our supported versions yet. However, we aim to exchange that package (#171) in order to be able to support Python 3.11 as well, and will keep you updated once this is done.
