This piggybacks on the media quality observer to also check whether the audio track changed and the change was in label, language, or role. Currently, this new event is triggered is `observeQualityChanges` is set. This could be moved to a separate config. I do play to add a test or two to the integration tests. For verifying the role/label, I was testing against this public test stream https://demo.unified-streaming.com/k8s/features/stable/video/tears-of-steel/tears-of-steel-desc-aud.ism/.mpd (though, it does seem to error out every so often). There might be other test streams. Angel One is a great one for language. Also, something that we noticed, but won't be part of this PR. The timing of this event is likely incorrect if the track was switched and safeMargin was set. We have some changes for this locally that we can PR, but there are some issues we found around devices for it, so, it isn't a straightforward change.
