Improvements for mainline

[foxel]

Some improvements from my side excluding the TTS adaptation:

• binary sensors are now really binary
• rtsp links are obtained from the camera, fixes issues with no high res stream
• device info has connections defined so that it can merge with the same devices from other integrations
• camera now supports stream integration

Thanks for your contribution!

I just updated to latest code with camera supports stream integration
then the live streaming in hass does not work (a blank white screen in the camera view)

Once I have removed the code below, the streaming works again for me.
Could we make this configurable?

    @property
    def supported_features(self) -> int:
        """Return supported features."""
        return SUPPORT_STREAM

@vin-w this piece of coffee just says that the camera is capable of providing a streaming URL.
You need to check that your HA stream integration works out disable it.
See requirements and details at https://www.home-assistant.io/integrations/stream/

@foxel Today I have fetched latest code + restarted the docker stack, it works now!
With the "Preload stream" checked, I don't have any more drop frame.

Thanks again for your code and make a happy home here.
