Maintenance Todos

[benfre]

The original repo by dawsonjon has not been updated in few years.
After forking, these is the things I would to do in the next few days.

• Upgrade to Python 3
• publish package to pypi (under different name)
• adapter to axi stream for input output
• test examples with Python 3
