Partitioned stac-geoparquet writes

We should provide a way for folks to write partitioned **stac-geoparquet**. Since there's an infinite number of ways folks might want to partition, we have to limit our scope by...

Currently, we can't write a **stac-geoparquet** with an empty `assets` structure: ```text GeoArrow(External(ArrowError("Parquet does not support writing empty structs"))) ``` Simple code to trigger the error (from the **stac** crate):...
