Redeploy to pypi once stashy is updated

[noahp]

Once stashy is updated, stash-py-stats should be able to be successfully deployed to pypi; at the moment since this package relies on a fork of stashy, we can only install from source, see:

pypa/pip#5566 (comment)

See these issues for the stashy update:

cosmin/stashy#109
cosmin/stashy#111

Note- this is enforced by pypi with the error when publishing:

HTTPError: 400 Client Error: Invalid value for requires_dist. Error: Can't have direct dependency: 'stashy @ git+https://github.com/noahp/stashy.git@f42707cb87fe7a50f77d739b00494720062fd06e' for url: https://upload.pypi.org/legacy/

I just pushed stashy 0.6 to PyPI, sorry for the long delay my job took a long detour from dealing with Python and with the changes to PyPI.org and Twine I never quiet got around to updating my setup to push new releases.
