Transform each input element into a sequence of output elements that is then flattened into the output stream. The returned sequence MUST NOT contain null values, as they are illegal as stream elements - according to the Reactive Streams specification.

Emits when the mapping function mapConcater returns an element or there are still remaining elements from the previously calculated collection

Backpressures when downstream backpressures or there are still remaining elements from the previously calculated collection
