Support zips of zips #69
Description
This zip contains zips that contain playable files.
It would be nice if each ZIP had a "View Contents" link, and for Unbox to be able/willing to vend up the files inside the zip of zips, so that Parchment etc. could play them.
Today, it's not even possible to manually create a "View Contents" link for those ZIPs. For example, if I copy the link https://unbox.ifarchive.org/1qt9bd9so7/orgc2006/easter.zip and paste it into the Unboxer homepage https://unbox.ifarchive.org/?url=https%3A%2F%2Funbox.ifarchive.org%2F1qt9bd9so7%2Forgc2006%2Feaster.zip I get an error message:
BadRequestError: Sorry, we don't support files from outside the IF Archive
