Not sure what grayskull did last time, but I did this manually based on upstream setup.py. This fixes the dropped idna dependency and allows a wider range for charset_normalizer. I need the latter to get to >= 2.0.2 (from 2.0.0) to fix a bug involving unicodedata2. Also, upstream only now requires chardet for Python 2.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.
