Bug fixes:
- Fix crash during startup when Sonos Bridge is present on network (see #90, basically seem issue as Boost, #88)
- Handle zones with only invisible zone players structurally, instead of whitelisting the devices. Should also work for future devices similar to Sonos Boost and Sonos Bridge.
- Revert the _ Lock Physical Controls_ change: both Sonos Boost and Sonos Bridge expose the GetButtonLockState and SetButtonLockState actions under DeviceProperties.
