The cancel() method of the ReadableStreamBYOBReader interface returns a Promise that resolves when the stream is canceled. Calling this method signals a loss of interest in the stream by a consumer.
Note: If the reader is active, the cancel() method behaves the same as that for the associated stream (ReadableStream.cancel()).
cancel() cancel(reason)
A human-readable reason for the cancellation. The underlying source may or may not use it.
A Promise, which fulfills with the value given in the reason parameter.
The source object is not a ReadableStreamBYOBReader, or the stream has no owner.
TBD.
