  Fix segmentation of last returns

segmentLastReturns now defines last returns as those points whose ReturnNumber
equals the NumberOfReturns when the NumberOfReturns is greater than 1.

This segmentation is used in both the SMRF and PMF ground segmentation filters,
so ground segmentation results may differ from what was previously returned.
