TEMPORARY SOLUTION (this will be replaced by a proper dependency manager in the future):

Convert a json object representing the dependencies of a project into the binary format accepted by quinoa

FORMAT:

{
    prefix? : str,
    modules : { name -> path },
    deps? : [ list of paths to qpk.json files ]
}
