update

Called to update new data from the vision system, which involves interpreting, collecting, or otherwise processing new vision data per frame.

This method should refresh `this.data` with the latest information from the vision system to be accessed with your methods on .getData().T (your VisionData class). `this.data` is automatically cleared upon each iteration, so opt to using realtime data in this method. This method will be called automatically once attached to a Vision instance.
