configure pause timeout

Hi, thanks for sharing go-chromecast - its great!

If you pause the playing content for greater than 20min, chromecasts "ambient" mode kicks in and begins displaying a slideshow. This would be great if there was a way to keep the connection alive - but attempting to unpause the stream results in nothing, and I do not see any errors in the go-chromecast ui log section of the tui.

Running go-chromecast -v -u uuid load sample.mp4 shows that after 20min the connections heartbeat stops, and "isIdleScreen":true. I am casting to a gen 3 dongle

I assumed timeout could be configured from the chromecast side, but was not so surprised to find out it's not possible - at least without enabling "developer mode" via adb (maybe). Even then people appear to have mixed results.

Do you have thoughts on potentially working around this? Yes, screen burn in needs to be considered - but 20min is too short imo.

Thanks for your time.

EDIT: Not sure how accurate this info is, but it references configuring the various timeouts from the app side, specifically the first comment. Ideally we could keep the connection alive regardless of chromecasts ambient mode - but I assume its not possible?
