Tests on github actions are not passing

Here's the log output:

fatal: not a git repository (or any of the parent directories): .git [WARNING]: error 128 while getting commit hash: b'', setting hash to None ImportError while loading conftest '/home/runner/work/lvmdrp/lvmdrp/tests/conftest.py'. /home/runner/work/lvmdrp/lvmdrp/tests/conftest.py:17: in <module> from lvmdrp.core.image import _parse_ccd_section core/image.py:28: in <module> from cextern.fast_median.fast_median import fast_median_filter_2d E ModuleNotFoundError: No module named 'cextern.fast_median.fast_median' Error: Process completed with exit code 4.

The error may originate in a failed compilation of the external libraries for fast_median. We need properly implement this external C++ library as an extension as documented here:

https://setuptools.pypa.io/en/latest/userguide/ext_modules.html

Custom compiler and options are also discussed, in the framework of setuptools, here:
