Added New Protocol to switch between all three modes. If switch[1:0]=2'b11, then we are in fusion display mode. Otherwise, we use switch[4] to select between edgOutput and colReduce. This will be useful for demonstrating our results during final checkoff. Note that switch[1:0] is also used to manipulate the hsv selector. We just have to make sure not to flick hsv selector all at once. Will test with different edge threshold values once we see the edge output
