The flashmap support saves the user from having to specify programmer,
program and patch XML files, it allows reading the flashmap.json either
among the flat files, or as part of a zip-container of all the parts.
Add dry-run tests for the two cases, by introducing a flashmap.json and
zipping up all the files, then run qdl on the two versions.
