Fix python3.12 build failure

[wangenau]

This should fix #62.

setuptools is now a required build dependency for Python 3.12, see https://cffi.readthedocs.io/en/stable/whatsnew.html#v1-16-0.

It wasn't super clear to me how the wheels that land on PyPI are generated. To test this I downloaded the current source distribution, modified the pyproject.toml file, and tested that the installation works.
Someone needs to make sure that this also works with your workflow/in the CI.

The same patch should be applicable to dftd4 and tblite.

Linked issues for reference: tblite/tblite#195 tblite/tblite#198

While at it, I have also updated the usage of random calls to replace some deprecated function calls.

I will have no access to the internet for the next two weeks and probably won't reply on this PR, sorry for that.
