Face detection tests

These are integration tests for the face detection service.

Setup

If no setup is performed the "default" camera will be used. To specify which camera to use, set the Camera.Index value as a User Secret before running the tests.

You also need to download the facial detection model face_detection_yunet_2026may.onnx and reference to it from Camera.Model in the User Secrets.

You have to sit in front of the camera with your face visible.
