ENH: use SubList for CompactListList access

Browse Source 
- this was previously a UList instead of SubList,
  but SubList supports better assignment of values

ENH: add invertOneToManyCompact

- returns a CompactListList<label> instead of labelListList, which
  allows for reuse as partitioning table etc and/or slightly reduced
  memory overhead
