Remarks
An unique id per face while the face is visible to the tracker.
If the face leaves the field-of-view and comes back, it will get a new id.
This is an optional field and may not be supported on all devices. If the id is Face.IdUnsupported, the leftEyePosition, rightEyePosition, and mouthPosition must all be null. Otherwise, they must either all be null or all be non-null. When devices report the value of key CaptureResult.STATISTICS_FACE_DETECT_MODE as CameraMetadata.STATISTICS_FACE_DETECT_MODE_SIMPLE in CaptureResult, the face id of each face is expected to be Face.IdUnsupported.
This value should either be Face.IdUnsupported or otherwise greater than 0.
