Ubooquity comics scanner should support expanded comics

The built-in comics reader is so painfully slow for me that I wrote a python tool which finds every CBR/CBZ in my directories and unpacks them to individual JPG files with the folder structure <publisher>/<title>/<volume>/<issue>/<pagenum>.jpg

Every tool I've tried fails to find any of the JPGs when they're expanded this way. It would be nice if Ubooquity could support it.
