Key changes:

• Implements affine transformation logic for coordinate conversion
• Adds two new scalar UDFs for X and Y coordinate transformation
• Extends benchmark infrastructure to support integer range arguments

Thank you!

Just curious: Is there also a RS_RasterToWorldCoord() that returns a Geometry?
