cameraundistort: Provide description for "settings" parameter in documentation
In the plugin description, "settings" parameter is described as "Camera correction parameters (opaque string of serialized OpenCV objects)". This description is very vague and lacks specific as to what exactly OpenCV object it expects, in what format they should be serialized and provided to the pipeline. Example pipeline omits giving actual example of the parameter, substituting it with question marks: settings="???"
I would be great if plugin description was extended to include actual settings parameters example and state what OpenCV object it expects and in what formats.
