Update software.cfg: This version of cryptography does have a setup.py file, but we need setuptools-rust (they advise to update pip, which I will try next if this here fails)

Update software.cfg: Trying another version (this one does not have a setup.py file) of cryptography that might hopefully work.

Update software.cfg, because cryptography>40.0.1 is required for asyncua. Also specified a version for asyncua, we want to make sure it will work in the future.
