The Subscriber object dispatches a
qualityScoreChanged
event when either the audio or video quality score changes for the subscriber.
The scores are a heuristic value representing the expected subscriber experience.
The values are integers ranging from 1 to 5, with the values corresponding to
bad, poor, fair, good, and excellent.
This is a beta feature.
