Screensaver isOn/isOff info?  #77

Hi,

Will one of the commands expose information related to the screensaver?

I would just like to know, if it's possible to check the current screensaver-state (on/off).

If there's a count, that's even more great - but I can work that part out with a simple datalogger.

My plan is to turn off the tv after a specific amount of time, if the TV is just showing the screensaver. I know there's auto off-function build in, but I'd like to handle it in Home Assistant. 😊 🤟...
