* The numpy.alen() function is deprecated. We use len() instead
* The use of pkg_resources is discouraged. We use importlib.metadata
instead. I also removed setuptools_scm get_version. I switch to
a simple call to "git describe", easier now that we use git flow
* The build fails with python3.10 if compiling wx from sources.
A fix in the Makefile will be proposed in a future commit.
