1.7.0: Has Python 2.7 classifiers but is Python 3+ only.

[alexdutton]

The 1.7.0 release adds async/await syntax but the Python 2 classifiers haven't been removed from the distribution metadata.

So that clients resolving for Py 2.7 don't pick the wrong release, would you be able to remove the Python 2 classifiers, make a new release, and yank the 1.7.0 version from PyPI?

Good catch!
Thanks for letting me know, I will have a look at this ASAP

@alexdutton I have bumped the version to 1.7.1 and yanked 1.7.0
Thank you for pointing out the issue
