Installation procedure does not ensure correct installation
Following the installation procedure in README.md + running pip install -e .[test]
does not ensure a correct installation. The bessel function unit test does not work for all users. They run fine on the CI/CD pipeline, so it is most likely a local issue.
It would be good to have a installation procedure that takes existing files and software on the machine into account. Once this is made, it should also be added to README.md
