The purpose of this rework is to use parent package archive as common
base for all the modules.
Warnings: some modifications might require some reviews, tests were done
but maybe not thoroughly enough.
Reworks:
- replaces deprecated DISTUTILS_USE_SETUPTOOLS by
DISTUTILS_USE_PEP517, with "setuptools" (DistutilsNonPEP517Build);
- integrates parent mechanism for base source;
- stores archive with ".gh" in its extension (PythonGHDistfileSuffix)
also use parent’s file;
- enables more architectures;
- adds Sphinx documentation support (to test further).
