Release 0.7

Try forcing Travis to deploy with Python 2.7

The latest python tooling has changed and seems to no longer support generating universal wheels. Maybe. It's not clear. But when I locally ``python setup.py sdist bdist_wheel``, I get a universal wheel from python2. But python 3.8 generates an "Instrumental_lib-0.6-cp38-cp38-linux_x86_64.whl", which PyPI refuses to accept. Maybe the newest versions of wheel/setuptools/whatever no longer support generating universal wheels. I have no idea. I just want the pain to stop.

Only deploy once, for Python 3.6

Since we only end up uploading an sdist anyway, this avoids repeat
uploads, which cause Travis to error.
