Reusable filter for checking the direction of a new state if it is in the correct orientation (forwards or backwards) by their arc length.
Especially, the following is checked:
arc length of this hit < arc length of the origin (backward) or > (forward) arc length of this hit > arc length of the hit before (backward) or < (forward)
All the arc lengths are calculated using a trajectory based on the last valid mSoP (always pointing in forward direction).
