- split
  
  public int split(BlockSplitter.Context context, WritableIntChunkChunk targetPositions, IntChunkChunk hashChunks, int inputChunksLogSize)
  
  Identifies the target hash block positions for a chunk of chunks in a target
  
  Parameters:
  
  context - The context kept for this operation
  
  targetPositions - A chunk of chunks where the chunk at position `k` contains the positions of the elements in the intermediary chunks to be inserted in the final block `k`
  
  hashChunks - The hash values for the intermediary chunks to be inserted
  
  inputChunksLogSize -
  
  Returns:
  
  The position of the targetPosition chunk that is full or -1 is all the keys were scanned and none of the targetPositions are full. Once -1 is returned, it is expected that all chunks in targetPosition have the size properly set.
