Archive support

[slundi]

Hello,

Sometimes I regroup images into an archive file (ZIP/CBZ, RAR/CBR, TAR/CBT, 7z/CB7)
Can you add some archive support ?

That's a bit different from how I intended to use fussel myself. Do you envision the python code unpacking the images at the time? If you have a good use-case and can figure out a way that might work feel free to submit a PR for it. However it does seem like a situation where we might support a "preprocesses" hook and let people writ their own scripts that might do something like unpack to a folder and rearrange things for their needs.
