Research direction

Inspect commit 23048fb6a3d1520dd1336371dc67ec6dc5fbd55a and the inheritance of IcebergScanTransformer. Trace the path that produces the `Unsupported input partition.` error in the Velox backend and verify the fix against an IcebergScan case; done means that error no longer occurs.
