Kontinuation opened a new pull request, #597:
URL: https://github.com/apache/sedona-db/pull/597

   ## Summary
   
   - **RS_Envelope**: Update to produce geometry output with item-level CRS 
propagated from the raster's CRS, instead of plain `Wkb(Planar, None)`
   - **RS_ConvexHull** (new): Returns the convex hull polygon of a raster from 
its four corner world coordinates. Unlike RS_Envelope (axis-aligned bounding 
box), RS_ConvexHull preserves the actual raster footprint for skewed/rotated 
rasters. Also outputs with item-level CRS.
