Building on Enterprise Linux 8 (RHEL/Alma/Oracle/Rocky)

The following patch is required for systems running python 3.6. (I would set up a pull request, but I am unable to do that at the moment.)

diff --git a/python/setup.py b/python/setup.py

+  ext_modules = cythonize(extensions, language_level=3)
  )

this prevents errors like the following:
