Update some tunings & swap to heading/distance/skew
* Tune down the velocity offset variances, which significantly
reduces the odds of horrible corrections killing the robot's
position.
* Swap over to using heading/distance/skew for localizer corrections.
* Tune noise values associated with the heading/distance/skew.
Had to lazily make some of the tests pass....
