Module quad 

Quad extraction and geometric primitives. Quad extraction and geometric primitive fitting.

This module implements the middle stage of the detection pipeline:

1. Contour Tracing: Extracting the boundary of connected components.
2. Simplification: Using Douglas-Peucker to reduce complex contours to polygons.
3. Quad Fitting: Heuristics to reduce polygons to quadrilaterals and verify convexity.
4. Sub-pixel Refinement: Intensity-based edge localization for maximum precision.
