* Only generate bindata if necessary * Only generate bindata if they are not up-to-date * generate a hash of the fileinfo and use that to keep up-to-date * Newer test is redundant * handle missing bindata and clean * Only update hash after successful write * switch to sha1 hash * Apply suggestions from code review Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> Co-authored-by: guillep2k <18600385+guillep2k@users.noreply.github.com>
