Originally the create and dispatch of stream data in the cue
alignment tests were separate to improve readability. The idea was
to separate building each stream and dispatching the streams muxed
together would make it easier to understand the streams.
However, coming back to the code, this did not hold up as it took just as
long to understand the code. So merging the two together allows for the
code to be more concise.
