use codecs module to decode quoted printable email bodys

[peritus]

We're using Python 3.5 and we kept getting this error when parsing emails:

Documentation:

    decode('quoted-printable')

The attached code fixes that by using the codecs module [https://docs.python.org/3.6/library/codecs.html] to parse the quoted printable email bodies

@peritus Actually, I've noticed that for my emails, the encoding is 'latin-1' instead of 'utf-8'. Any chance you could add an encoding='utf-8' default parameter to the method and then change the decoding step to read:

body = decode(encoded_body, 'quopri_codec').decode(encoding)

Thanks, Andrew
