python-vcs-versioning: add new package (version 1.0.1)

vcs-versioning provides the core VCS version inference logic that was
extracted from setuptools-scm into a standalone library. This enables
other build backends to use the same version inference without a
setuptools dependency.

Required as a new dependency for setuptools-scm >= 10.0.0.
