   The current design of CompetitiveImpactAccumulator treats norms in -128..127
   as a special case that should be optimized. This commit goes a bit further by
   treating it as the normal case, and only ever adding impacts to the TreeSet if
   the norm is outside of the byte range. It avoids a number of operations on
   TreeSets like adding impacts or removing redundant impacts.
