Fixes desync in polarity tracking between dataTick and tick for prediction and smoothing.
Simplifies prediction logic (uses reduce instead of a buffer with forEach).
Resets polarity tracking based on a reference rotation (HMD).
- This should hopefully fix flipping on resets.
- There is a maximum of 180 degrees rotation between a tracker and the headset when resetting because of this. We can possibly mitigate that in the future by aligning the spaces in a smarter way, but I think this is a fairly reasonable compromise for now. Perhaps a second step can be performed after resetting all trackers that aligns the spaces based on the hierarchy?
Fixes snapping on settings changes (using raw rotation instead of adjusted) introduced by #1352.
