Upgrade to OpenCV 4.5.5

Certain corrupt media files can cause Workflow Manager to crash. Upgrading OpenCV allows Workflow Manager to detect the corrupt video and prevent further processing.

We determined that although most Python components have opencv-python>=4.4.0, that is sufficient to allow OpenCV to detect the corrupt video that motivated the C++ OpenCV upgrade to 4.5.5.

Specifically, the earliest match is opencv-python==4.4.0.40 and that fails to read the frame w/o crashing.

Linking to different ffmpeg libraries also fixes the issue. We saw that when @brosenberg42 determined the Ubuntu version of the OpenMPF WFM detects the issue.

Most likely, the Python version of OpenCV is linking to a different version of ffmpeg, while allows it detect the issue although it's an older version of OpenCV.
