add large scale/batch signature renaming

[ctb]

something we could usefully use for database construction (including for private database construction in genome-grist, e.g. dib-lab/genome-grist#130) is the ability to rename sketches via a spreadsheet/CSV file.

I was thinking of something like this:

sourmash sig rename --names-from-csv <csvfile> <list of input sigs> -o <zip collection>

where <csvfile> could contain a list of identifier-name pairs, specifying what the output names should be based on the identifier; or a list of md5sum-name pairs, for same.

ref #1315, which is more about assigning name at time of sketching.
