Feature Request: Night Mode Sensor Entity

[monstermuffin]

Is your feature request related to a problem? Please describe.
I have 2 outdoor cameras, one of them faces into a street lamp as as a consequence, night mode is not ever enabled when it should be. The other camera does not have this issue, so I would like to create an automation to be able to turn on/off night mode on one camera based on the other.

Describe the solution you'd like
I would like a sensor entity that reports whether or not night mode is currently enabled on the camera (outside of the night vision on/off/auto setting). If I am able to read the status of night mode on the cameras I can create an automation based on it.

Additional context
I'm not sure if this reporting is possible, but if it is then this would solve an issue for me and I'd hazard be a generally useful sensor entity.

Thanks :)
