      I've removed the newtonRaphsonIterate algo because in benchmarking it
      wasn't noticeably faster than binarySubdivision, indeed removing it
      usually improved times, depending on the curve.
      I also removed the lookup table, as for the added bundle size and loop we're
      only cutting ~4 or so subdivision iterations. I bumped the max iterations up
      to 12 to compensate and this still tended to be faster for no perceivable
      loss in accuracy.
