Installation failing on Windows due to encoding issue

Hi Max,

sweet library! What a breeze it is to use pandas with a Bayesian network!

I stumbled upon an installation issue, that's easy to fix:

Problem

When installing hedgehog on Windows via $ pip install git+https://github.com/MaxHalford/hedgehog this error occurs:

Explanation / Solution

This error is caused by Windows' default encoding cp1252. For using utf-8 across platforms, setup.py can be adjusted in line 6:

    return open(os.path.join(os.path.dirname(__file__), fname), encoding="utf-8").read()

Solution was tested on Windows. No change should be noticed on unix systems.
