BufferBandwidthRule is an enhanced version of BandwidthRule The change is that if the BandwidthRule recommends a lower bitrate than the current one, the BufferBandwidthRule overrides that low recommendation with the current bitrate if there are enough fragments in the buffer (we can afford to stick to this bitrate for now, since we have a large enough buffer)

參數

	`metricRepository:MetricRepository` — The metric repository from which to retrieve the necessary metrics

	`weights:Vector.<Number>` — The weights of the fragments (first values are the weights of the most recent fragments)

	`bufferFragmentsThreshold:Number` — The number of fragments in the buffer above which no lower bitrates are recomended. For example, assume the bandwidth has a value of 3000 kbps and the actual bitrate is 5000 kbps. If the number of fragments in the buffer is below the threshold, the rule will recommend 3000 kbps; otherwise, it will recommend 5000 kbps
