docs: Create a boolean SArray by checking the keys of an SArray of
          dictionaries. An element of the output SArray is True if the
          corresponding input element's dictionary has all of the given keys.
          Fails on SArrays whose data type is not ``dict``.
  
          Parameters
          ----------
          keys : list
              A list of key values to check each dictionary against.
  
          Returns
          -------
          out : SArray
              A SArray of int type, where each element indicates whether the
              input SArray element contains all keys in the input list.
