Is your feature request related to a problem or challenge?

The existing ParquetWriter and LocationGenerator cannot generate a path with partition info, and can only generate path like

/table/data/part-00000.parquet

Describe the solution you'd like

Ideally, we need to be able to generate paths like the following based on the partition values

/table/data/id=1/name=alice/part-00000.parquet

I would be willing to contribute to this feature with guidance from the Iceberg Rust community
