Merges an array of readable streams and returns a new readable stream that emits data from the individual streams as it arrives.
If you provide an empty array, the stream remains open but can be manually ended.
#### MergedStream
_Type_: stream.Readable
A single stream combining the output of multiple streams.
##### MergedStream.add(stream: stream.Readable): void
Pipe a new readable stream.
Throws if MergedStream has already ended.
##### MergedStream.remove(stream: stream.Readable): Promise
Unpipe a stream previously added using either mergeStreams(streams) or MergedStream.add(stream).
Returns false if the stream was not previously added, or if it was already removed by MergedStream.remove(stream)`.
The removed stream is not automatically ended.
