Is wfuzz python 3.8 compatible? no badge in readme currently

# Issue template

## Context

**Please check:**

- [x] I've read the docs for [Wfuzz](http://wfuzz.readthedocs.io/)

See title.
I can't check all functionality against different python versions right now, but I'm also experiencing #180 for example with python3.8.
As there is no 3.8 badge in the readme I am not sure if it is officially supported / everything should work.
