   `RS_AsGeoTiff(raster [, …]) -> binary` — encode a raster as a GeoTIFF and 
return the bytes, with optional compression and tiling overloads.
   
   Split out of the GDAL raster draft #704, reusing that implementation. Tests 
were reworked onto the RasterSpec harness (no external `.tiff` fixtures, and 
the roundtrip check reopens the bytes via the merged GDAL reader instead of the 
not-yet-split RS_FromGDALRaster); adds a RasterSpec-based benchmark and SQL 
docs.
   
   N-D handling is deferred (GeoTIFF is inherently 2-D/multiband) — export 
relies on the existing N-D→2-D plane decomposition and hasn't been given 
dedicated N-D semantics here.
