There are some corner cases with streams that cause them to not emit
finish close or end events which in turn means that code liseting for
these events directly may end up hanging forever. Use stream.finished
to detect end of streams which will handle these cases correctly.
Add splitter based on LineSplitter which splits lines in reverse from a
reverse stream created from the added createReverseReadStream function.
Enables line processing of files starting from the last line and going
towards the first.
Pull the LineSplitter class out of lib/factorio to its own stream module
and refactor it to be based on stream.Transform. This allows composing
with other streams by piping it around.
