Some model version archive only contain one file with a varying name.

When that happens, the file must be renamed to a constant string in order to be easily usable by generic workers.

Please add a new CLI option --rename=XXXX that will rename the single file found to that specific string. The tool should crash when encountering multiple files when that option is enabled.
