Add unit tests for PDF Packager converter functionality
- Implement tests for converter properties, ensuring correct input and output formats. - Add tests for chip parsing, covering various image, pdf_image, and pdfa chip formats. - Include tests for the isArchiveOutput and getOutputFileName functions. - Mock execFile for testing the convert function, verifying command execution and output file creation. - Ensure all chips are parseable and validate the completeness of chip categories.
