v3.2.0

CHANGES:

• Base64_rfc2045.decode can now progress on many input errors, allowing
  clients to make forward progress by discarding a single character and
  trying to continue. This allows, for example, newlines and other invalid
  characters to be discarded. (#34 @tiash, review by @dinosaure @avsm)
• Add more test cases for RFC2045 (#34 @dinosaure)
• Improve README toplevel output example (#28 @djs55)
