Motivation for this change

opencv2 is essentially EOL and has security concerns

The package's setup.py itself does list its opencv dependency as opencv-python>=3.0,<4.0 so this "should be fine".

It's a tricky package to test - the tests are present in the github repo, but even then they are very much not self-contained, and none of the tests seem to cover any of the opencv-provided functionality anyway.

The package itself is a bit problematic tbh, with undeclared runtime dependencies on cli tools like ffmpeg being present.
