Build fails on python3.9 on gravitron

pip install ciso8601 fails on gravitron using python 3.9, it works just fine using 3.8. I think it might be a simple setup issue, but I am not sure where the complier flags are set.

I'm also running into this trying to install inside the continuumio/miniconda3 Docker container.

$ docker run -it --rm continuumio/miniconda3 /bin/bash
