docstr: Begin an incremental save of the Cuckoo filter `key`.
  
  This is useful for large Cuckoo 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.
  For more information see `CF.SCANDUMP <https://redis.io/commands/cf.scandump>`_.
