❗IMPORTANT ❗Security issue in `opencv-python`

This PR provides fix for the following security issue:

opencv-python versions before v4.8.1.78 bundled libwebp binaries in wheels that are vulnerable to GHSA-j7hp-h8jx-5ppr. opencv-python v4.8.1.78 upgrades the bundled libwebp binary to v1.3.2.

We advise all clients using inference to migrate, especially in production environments.
