beam.io.parquetio.ReadAllFromParquet from compressed tar.gz files

Hi

Is it possible to read from tar.gz compressed parquet files? Is there a technical limitation to allow for this to happen? It seems to be hardcoded here to read only UNCOMPRESSED parquet files: https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/parquetio.py#L227
