    https://github.com/apache/orc/pull/257
  
    Part of what we absolutely need in RLEv3 is zero suppression for the whole row batch.
So that if you have integers like:
    
    - 1000
    - 2000
    - 3000
    - 10000
    - 4000
    - 1000
    
    it will record 3 for the number of zeros and encode:
    
    - 1
    - 2
    - 3
    - 10
    - 4
    - 1
