Query output fields does not support bool field

Steps/Code to reproduce:

1. create dataFrame with fields [int64, float, float_vec, bool]
2. construct collection from dataframe (create collection and insert)
3. flush and load
4. query with expr: int64 in [0, 1] and output all scala fields

    def test_query_bool(self):
        self._connect()
        df = cf.gen_default_dataframe_data()
        bool_values = pd.Series(data=[np.bool(i) for i in range(ct.default_nb)], dtype="bool")
        df["bool"] = bool_values
        self.collection_wrap.construct_from_dataframe(cf.gen_unique_str(prefix), df,
                                                      primary_field=ct.default_int64_field_name)
        assert self.collection_wrap.num_entities == ct.default_nb
        self.collection_wrap.load()
        term_expr = f'{ct.default_int64_field_name} in [0, 1]'
        self.collection_wrap.query(term_expr, output_fields=["*"])

Expected result:

Query result output int64, float and bool fields

Actual results:
