/**
* Create new `AdaptationStream` whose task will be to download the media data
* for a given Adaptation (i.e. "track").
*
* It will rely on the IRepresentationEstimator to choose at any time the
* best Representation for this Adaptation and then run the logic to download
* and push the corresponding segments in the SegmentSink.
*
* @param {Object} args - Various arguments allowing the `AdaptationStream` to
* determine which Representation to choose and which segments to load from it.
* You can check the corresponding type for more information.
* @param {Object} callbacks - The `AdaptationStream` relies on a system of
* callbacks that it will call on various events.
*
* Depending on the event, the caller may be supposed to perform actions to
* react upon some of them.
*
* This approach is taken instead of a more classical EventEmitter pattern to:
* - Allow callbacks to be called synchronously after the
* `AdaptationStream` is called.
* - Simplify bubbling events up, by just passing through callbacks
* - Force the caller to explicitely handle or not the different events.
*
* Callbacks may start being called immediately after the `AdaptationStream`
* call and may be called until either the `parentCancelSignal` argument is
* triggered, or until the `error` callback is called, whichever comes first.
* @param {Object} parentCancelSignal - `CancellationSignal` allowing, when
* triggered, to immediately stop all operations the `AdaptationStream` is
* doing.
