Pykefcontrol

Info ℹ️
- Pykefcontrol is now **compatible with LSX II and LS60** !

New Feature ✨
- Add `speaker_model` and `firmware_version` properties.

Warning ⚠️
- `song_sattus` argument of the `poll_speaker` method is now deprecated. Please use `poll_song_status` instead. It has the same behaviour.

Info ℹ️
- Pykefcontrol should be compatible with **LSX 2** and **LS60** but testers are needed. If interesed, see [here](https://github.com/N0ciple/pykefcontrol#%EF%B8%8F-help-test-pykefcontrol-on-the-lsx-2-and-ls60)

Bug Fix 🐛
- modify the method `poll_speaker` to prevent it from failling if `song_status` is not properly returned by the speaker
- regenerate the queue_id if the parameter `song_status` is changed by the user in the method `poll_speaker`

Bug Fix 🐛
- Correct a critical bug in v0.6 which was caused by a typo.

New Feature ✨
- Add parameter `song_status` to the method `poll_queue` to enable or disable `song_status` polling. See **README.md** for details.

Add method `poll_speaker` that returns the last changes made to properties since the last poll.
See README.md ( **Information polling**) for more details.
