ENH: memory/efficiency improvements: renumbering, bandCompression (#2430)

- support direct processing of CompactListList instead of requiring
  a conversion to labelListList for bandCompression and renumbering
  methods.

- manage FIFO with CircularBuffer instead of SLList (avoids
  allocations in inner loops). Invert logic to use a bitSet of
  unvisited cells, which improves looping as the matrix becomes more
  sparse.

- fix missed weighting in bandCompression (same as #1376).
  In polyTopoChange, handle removed cells immediately to simplify
  the logic and align more closely with bandCompression.

STYLE: enclose bandCompression within meshTools namespace

ENH: PrimitivePatch pointFaces with DynamicList instead of SLList
