docstr: Begin an incremental save of the bloom filter `key`.
  
  This is useful for large bloom filters which cannot fit into the normal SAVE and RESTORE model.
  The first time this command is called, the value of `iter` should be 0.
  This command will return successive (iter, data) pairs until (0, NULL) to indicate completion.
