Improvement in Conversion Accuracy
Introduced the "Transformation using Least Squares Method" function in contour conversion. Generates the optimal approximating polygon at a distance of 1 pixel from the contour line.
Achieves significantly higher accuracy than the conventional tracking-based L2 approximation.

Also introduced post-processing to reduce the deviation from the core line in the core line conversion.
