add query filename export #3
Description
We often get multiple cont.restored.t0 images: an original, a .conv version, sometimes an .alt version. We usually want the .conv version if it's available.
Writing a CASDA query result out to a file would be useful for handling these. For example, perform a --dry-run query, write out the matching filenames, discard any products without the .conv suffix, pass the modified file list to a new query for download.
Running a verbose query prints the filenames out to the log, so most of the work is already done.
