Add unit tests for MediaInfo frame class detection

- Created a JSON file containing various test cases for different video resolutions and their expected frame classes.
- Implemented a pytest test script that loads the test cases and verifies the frame class detection functionality of the MediaInfoExtractor.
- Utilized mocking to simulate the behavior of the MediaInfoExtractor and its video track attributes.
