cs_util version

[martinkilbinger]

This error occured:

ImportError: cannot import name 'get_cosmo' from 'cs_util.cosmo'
(/usr/local/lib/python3.12/site-packages/cs_util/cosmo.py)

The container has cs_util==0.2.1 (PyPI release), which doesn't have get_cosmo. But pyproject.toml already
documents that this repo needs cs_util's develop branch, not PyPI:

Track cs_util's develop branch directly (git dependency) rather than a
PyPI pin: ... cs_util get_theo_c_ell / get_theo_xi / PLANCK18 in
cs_util.cosmo, which land via CosmoStat/cs_util#76 ...
"cs_util @ git+https://github.com/CosmoStat/cs_util.git@develop",

This can be fixed by setting APPTAINERENV_PYTHONPATH.
