When using visl in automated tests, we need to have output frames that can be compared to reference frames or hash of those to validate that the whole pipeline is working properly. Add a "stable_output" module parameter to make sure that a given input stream always outputs the same frames. This is done by skipping information like queues status and pointer values. This also adds some stable variation in the frames so that different input give more different output.
