> When using {{write_metadata}}, {{kwargs}} can be used to pass a FileSystem to
> a ParquetWriter. However, those {{kwargs}} are not passed to
> {{read_metadata}} later on despite the function accepting a filesystem
> argument.
> This creates an error when trying to write metadata on a S3FileSystem for
> example.
