This fixes a huge bug when depending on state values inside the callback of the frameProcessor. As the frameProcessor had an empty dependency array it always called a stale function identity callback of the worklet which got passed initially. I.E onCallback calls a function which holds an if clause which depends on a useState value it has never seen the new useState value if it changed as the new identity/recreated callback function would not be used inside the Worklet and frameProcessor

I.E callback prop calls a function which holds an if clause which depends on a useState value, it has never seen the new useState value if it changed as the new identity/recreated callback function would not be used inside the worklet and frameProcessor.
This fix is important to prevent confusion. I had to debug it for 4 hrs :P
