Issue with release 0.9.16 and Python 3.6

[MatteoH2O1999]

Release 0.9.16 is classified as compatible with Python 3.6 while it is not

Bug description Latest release (v0.9.16) is classified by PyPY as being compatible with Python 3.6 while support for it has been dropped.

Reproduction steps

1. Install Python 3.6
2. Install pyre-check
3. run pyre check
4. Error with line `from future import annotations

Expected behavior PyPI should not let me download version 0.9.16 but instead recognizing that the last compatible version is 0.9.15

Logs

In general the error looks something like this:

Possible fix #670 should fix this issue for future version but 0.9.16 is released already so I don't really know how to solve this issue.
