Release v0.3.3

--------------

* Support Python 3.7.

  * Python 3.7 mandates PEP 479 which made StopIteration within a
    generator raise RuntimeException.

  * The urllib.parse.quote function now follows RFC 3986 and does no
    longer convert the `~` character.

  * Importing ABCs from `collections` will no longer be possible with
    Python 3.8, must then import from `collections.abc`.

* WiFi and Bluetooth Records print attribute keys in sorted order to
  have consitent output in documentation embedded tests (doctest).
