Add Shortcut for spatial.intersects procedure (#412)

Implemented a shortcut for the `spatial.intersects` procedure to improve performance.
The update bypasses the full geometry intersection check when the requested polygon is a rectangle (without hole) and the target geometry is entirely contained within the search window.
This optimization reduces unnecessary computations, enhancing the efficiency of spatial intersection operations.
