This method simply allows writing the call to

streamTransformer can return any stream.
Whether the returned stream is a broadcast stream or not,
and which elements it will contain,
is entirely up to the transformation.
This method should always be used for transformations which treat the entire stream as representing a single value which has perhaps been split into several parts for transport, like a file being read from disk or being fetched over a network. The transformation will then produce a new stream which transforms the stream's value incrementally (perhaps using Converter.startChunkedConversion). The resulting stream may again be chunks of the result, but does not have to correspond to specific events from the source string.
