Neat. But hasn't Niko Sams worked on something like that already? Or has this been a joint effort? Would be a pity if there was parallel development going on. But great to see that we have a solution for this. 
If this gets into master then in the future we should find some generic way to unzip stuff. I like how it's done in this code but if we could find something that works across Marble that would be even better.
