Creates a SourceTOut, TMat which when materialized will return an Stream which it is possible to write the ByteStrings to the stream this Source is attached to. This Source is intended for inter-operation with legacy APIs since it is inherently blocking. You can configure the default dispatcher for this Source by changing the "akka.stream.blocking-io-dispatcher" or set it for a given Source by using CreateDispatcher(String). The created Stream will be closed when the SourceTOut, TMat is cancelled, and closing the Stream will complete this SourceTOut, TMat.
