error with python 3.6

[tofulm]

in styler.py :
change :
L64 return list(filter(lambda val: val.startswith('#'), values))[0]
L70 bg = list(filter(lambda val: val.startswith('bg:'), values))[0]

and in renderer.py
change :
L63 : stream.write(out.decode('utf-8'))

It's ok with this change.

I'll try to get a new version on PyPI tomorrow, if I haven't by Sunday then please call me out on it.

Thanks fellow markdown enthusiasts!
