Suggestion: chunk files list, stdout export

[comendantmc]

It would be nice to be able to produce a list of chunk files when using --mode select instead/in addition to the selection csv.

For the --mode export would also be very nice to export into stdout to use it something like this:

ssh 0.0.0.0 "java -jar mcaselector... | gzip" | pv > export.tar.gz

It would really make the tool ten times more powerful for me.
