py-rfc3986: updated to 1.4.0

1.4.0:

Security

- Prevent users from receiving an invalid authority parsed from a malicious
  URL. Previously we did not stop parsing the authority section at the first
  backslash (``\\``) character. As a result, it was possible to trick our
  parser into parsing up to the first forward-slash (``/``) and thus
  generating an invalid authority.

Bug Fixes and Features

- Add ``from_uri`` to ``URIBuilder`` to allow creation of a ``URIBuilder``
  from an existing URI.

- Fix a typographical error in our documentation.
