py-curtsies with recent python3

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

Is there a way to conditionalise the requires.txt for this package,
based on the version of python in use, given that there is no
additional typing module for later pythons (I think the last to have
it was 3.4, but am not sure anymore)? This stops e.g. bpython from
working with these until
/usr/pkg/lib/python3.7/site-packages/curtsies-0.3.0-py3.7.egg-info/requires.txt
(for instance) is manually modified (by just taking 'typing' row out).
