Support python 2 and 3

[bix0r]

Goal

Support both python version 2 and 3.

Design

This seems to be the simplest way of support both versions. There are other ways, but this felt good.

Changeset

• Minor fix for missing headers if an error occurs
• Support both python 2 and 3
• Add info about python 3 support

Testing

Did some curl based tests with versions 2.7.18 and 3.8.10

Hi @bix0r,

Thanks for this. We are going to look to get this reviewed and merged in as soon as priorities allow.
