Description

GeoParquet spec 1.1 added a column covering metadata, it specifies a struct column containing bounding boxes to accelerate spatial queries. The GeoParquet writer of Apache Sedona could support this metadata in 2 ways:

1. The DataFrame being written already has covering columns, GeoParquet writer only write proper covering metadata to geoparquet metadata.
2. Automatically write bounding boxes to covering columns.
