  Minor updates to several filters

Initial focus is on updating static filters to always register official
Dimensions.

* LiTreeFilter now registers existing ClusterID instead of custom
  TreeID.

* LOFFilter now registers existing NNDistance instead of custom
  KDistance.

* OptimalNeighborhoodFilter now registers existing OptimalRadius and
  OptimalKNN.

* Register the following as "official" Dimensions: Coplanar,
  Eigenvalue0, Eigenvalue1, Eigenvalue2, LocalOutlierFactor,
  LocalReachabilityDistance, Miniball, PlaneFit, RadialDensity, Rank,
  Reciprocity

While updating Dimensions, also took the opportunity to:

* Be more explicit about datatypes, instead of relying on auto, to
  improve readability.

* Use PointView range-based for loops where it make sense. Generally
  makes code a little more succint.

* Do not pass KDIndex as frequently, when it can typically be grabbed
  off the view at no cost.
