      In ARROW-134, we added a workaround for Pandas NaT objects in the pandas test. We should encode NaT datetimes as BSON null in the write() function.

      Encoding a pandas.NaT object results in an error:

      bindings/python/test/test_pandas.py:114: in round_trip
    res = write(self.coll, data)
bindings/python/pymongoarrow/api.py:394: in write
    enc_tab = RawBSONDocument(encode(next(tabular_gen), codec_options=codec_options))
../../work/pycharm/mongo-arrow/lib/python3.10/site-packages/bson/__init__.py:1021: in encode
    return _dict_to_bson(document, check_keys, codec_options)
