System information

• TensorFlow.js version (you are using): @tensorflow-models/face-detection@1.0.2
• Are you willing to contribute it (Yes/No): Yes

Describe the feature and the current behavior/state.
Currently the TFJS Face detection model doesn't allow for configuring the minimum confidence score threshold while this appears to be possible in MediaPipe itself. Previously it seems like the TFJS blazeface model returned a probability field.

Is it possible to add either of these so that we could filter out faces based on their confidence threshold or probability?

This other relevant issue tensorflow/tensorflow#62683 mentions that the media pipe short range documentation shows that a detection confidence score should be returned.

Will this change the current api? How?
Would need to add some configuration to set the minimum thresholds or change the output to return a probability.

Who will benefit with this feature?
Users of TFJS face detection

Any Other info.
