docs: Filter an SArray of dictionary type by the given keys. By default, all
          keys that are in the provided list in ``keys`` are *excluded* from the
          returned SArray.
  
          Parameters
          ----------
          keys : list
              A collection of keys to trim down the elements in the SArray.
  
          exclude : bool, optional
              If True, all keys that are in the input key list are removed. If
              False, only keys that are in the input key list are retained.
  
          Returns
          -------
          out : SArray
              A SArray of dictionary type, with each dictionary element trimmed
              according to the input criteria.
