fully parse git context #35
Description
The package-related sender info (package name, commit hash, etc.) should all be populated via setuptools_scm and git describe. Most of this gets into the version object in setuptools, but it does not all make it into metadata which is easy to reach when creating a scarab.VersionSemantic in the package at runtime.
One possible solution is to leverage writing a version.py file with a format statement, in conjunction with a custom git describe if needed.
