Parent: #989 Depends on #991. Parquet's GeoStatistics column-chunk metadata carries a 4D bounding box (min/max for X, Y, Z, M) and the set of geometry types present. Spec: [Parquet Geospatial types](https://github.com/apache/parquet-format/blob/master/Geospatial.md). Plumb the writer in `table/internal/parquet_files.go` to emit GeoStatistics when a geo column is flagged; the parquet-go library exposes the API once the column type carries the geo logical type. The reader extracts GeoStatistics into the existing internal column-stats struct so downstream pruning sees it as if it were any other typed bound. Tests assert GeoStatistics present on round-tripped parquet plus a golden fixture from a Java-produced geo parquet for cross-client coverage. -- This is an automated message from the Apache Git Service.
