Extracting files from CD-I image

[gizahNL]

Hey! Thanks for writing this. I'm looking to extract all files from a CD-I disk however I'm not really having luck. The master branch doesn't like reading my image at all, the rewrite branch requires a "recipe" file, however it's unclear to me as to what would be the format for that file.
I've tried just using the JSON output of the cdi_info_json tool as recipe input, however that seems to fail as well.
