PIggyback on #916 -- CBZ internal files with no leading digits

**Is your feature request related to a problem? Please describe.**
#916 provided the CBZ feature for viewing in browser, but doesn't sort internal information correctly if those files within the archive have no leading zeroes (i.e. 1,2,3,4,5,6,7,8,9,10,11... will become 1,10,11,12... when viewed)

**Describe the idea / solution you'd like**
Either automatically smart enough to figure out order, or an option in control panel to tell it to sort the files in a 'human read' fashion

**Describe any alternatives you've considered**
This is a feature-set of similar readers like Komga, but it would be nice to have in CopyParty
