fix: Pin setuptools to last supporting Py 2.7

[bmedx]

PyPI is deprecating non-SNI clients from connecting and downloading packages in a rolling blackout: https://github.com/pypa/pypi-support/issues/978

This seems to have hit us because we have a pinned version of setuptools that pre-dates the SNI implementation. This PR bumps setuptools to the last version supported in Py 2.7.
