* Transform this stream by applying the given function to each of the elements
* as they pass through this processing step. The function returns a `Future` and the
* value of that future will be emitted downstream. As many futures as requested elements by
* downstream may run in parallel and each processed element will be emitted downstream
* as soon as it is ready, i.e. it is possible that the elements are not emitted downstream
* in the same order as received from upstream.
* value of that future will be emitted downstream. The number of Futures
* that shall run in parallel is given as the first argument to ``mapAsyncUnordered``.
* Each processed element will be emitted downstream as soon as it is ready, i.e. it is possible
* that the elements are not emitted downstream in the same order as received from upstream.
*
* If the function `f` throws an exception or if the `Future` is completed
* with failure and the supervision decision is [[akka.stream.Supervision.Stop]]
