@ioannisj would be cool to do the same on iOS if not throttling yet

iOS implementation is using a timer currently. When the timer fires we check if layoutSubviews was called (which would signal that something changed on the screen). So not debouncing, kind of throttling. This means, however, that the timer is still active even when the app is idle which can be improved (we just ignore if layoutSubviews was not called). Also, configuration option is still debouncerDelay which is a bit misleading. I can revisit the approach and ship a minor version along with start/stop recording
