Description

We still have an old opencv dependency in the tests, see here: https://github.com/lightly-ai/lightly/blob/2b215aa5d19b50515f280c1b0181f2f135cbc93f/tests/data/test_VideoDataset.py#L11

We should refactor the test(s) to not rely on opencv and remove opencv from all requirements files.

Contributor guide

Research direction
Search for all imports and usage of 'cv2' or 'opencv' in test files under tests/. Replace opencv functionality with alternatives like PIL (Pillow) or numpy as needed. Remove opencv from all requirements files (e.g., requirements.txt, setup.py, etc.). Run the test suite to ensure nothing breaks.
