Support parquet file format

[Dogfalo]

Describe the new feature being added
It would be good if this can support parquet files since they can be loaded and saved much faster than CSV files. This is more apparent as the size of the file begins to grow. source

How will this feature improve this extension
I think this is an even better use case for what has been built. Although it is useful to edit CSV's, the native jupyterlab editor can do that. Since the parquet format is not human readable, it is not possible currently for a user to modify that without loading it into pandas and then resaving it.
