HIC: Improve AccelerationClassifier
Apply a bunch of improvements to the acceleration classifier:
- When dragging from the edges, we get some delay without
movement between the DOWN and MOVE, which confounds the
classifier. Now discounts data segments where the delay
does not match the expected 16ms.
- The distance ratio did not compensate for differences
in sampling. If it does it's equivalent to the speed
ratio however. The distance ratio was removed and the
impact of the speed ratio score doubled.
- If we cannot calculate the ratio, no longer penalize
the traces for this.
