Feature request: compact destination image after backup

When SD! does a Smart Update to a disk sparse image, disk space is not reclaimed when an old file is deleted from the image. So the image file keeps growing even if the source volume doesn't. (I've been backing up 80GB of data but my image file was up to almost 100GB.)

The terminal command
hdiutil compact /your/drive/image.sparseimage
can be used to reclaim this wasted space. But it takes quite a while to run, especially if your image file has a lot of this garbage in it.

It would be nice if SD! had an option to automatically run this command at the conclusion of a backup to a sparse image.
