Added a 2nd order IIR lowpass filter to velocity, alpha = 0.1 was tested in python and yielded this
Added requirement that we see 5 consecutive readings below the velocity threshold to trigger activation. This corresponds to the orange line on the above graph going high. Note that due to the coast phase condition we would only be looking at it starting around sample 5250 in the graph, so the false positives at boost are not a concern.
