Add a chunks_to_gzip function.
This allows the _record_to_data code to build up a list of chunks,
rather than requiring a single string.
It should be ~ the same performance when using a single string, since
we are only adding a for() loop over the chunks and an if check.
We could possibly just remove the if check and not worry about adding
some empty strings in there.
