Provide sdist/git tag for delta-kernel-rust-sharing-wrapper

[bollwyvl]

For downstreams such as conda-forge, it would be lovely to have either:

• a .tar.gz uploaded to PyPI
  • this (and the main python library) should also include the LICENSE file
• a predictable tag pattern in git, e.g.
  • https://github.com/delta-io/delta-sharing/releases/tag/py-rust-wrapper-v0.1.0

And, of course, a meaningful version pin between the "user requested" delta-sharing-python package and the rust wrapper (a la #552) in setup.py (or, even better, pyproject.toml).
