Module refine 

Pluggable subpixel-refinement backends.

All refiners implement the CornerRefiner trait and are addressed through the user-facing RefinerKind enum. Default settings preserve the historical center-of-mass behaviour.

• center_of_mass — legacy 5×5 weighted centroid on the response map. Cheap; the default.
• forstner — gradient structure-tensor refinement on the image intensity patch.
• saddle_point — quadratic surface fit, robust to mild blur.
• radon_peak — Radon-projection refiner along candidate axes; robust to blur and low contrast.
