Sonos use common firmware version

[jjlawren]

Breaking change

The device associated with Sonos speakers will report a different firmware version, switching to the more common version.

Proposed change

This changes from an internal version to the one that's user-facing everywhere else.

Example from speaker:

>>> s.get_speaker_info()
{'zone_name': 'The Moon', 'player_icon': '/img/icon-S12.png', 'uid': 'RINCON_AABBCCDDEEFF1400', 'serial_number': 'AA-BB-CC-DD-EE-FF:2', 'software_version': '63.2-88230', 'hardware_version': '1.20.1.6-1.1', 'model_number': 'S12', 'model_name': 'Sonos Play:1', 'display_version': '13.1', 'mac_address': 'AA-BB-CC-DD-EE-FF'}
