Algorithm is incorrect to find paths

the current one is incorrect.
https://github.com/iyotetsuya/RectangleDetection/blob/823dc19fce41abad018997957547657cabcb84f5/app/src/main/java/io/github/iyotetsuya/rectangledetection/utils/OpenCVHelper.java#L164

rough idea:
1. use four points to get center point
2. get angle values from the center point, (x,0) and each one of 4 points.
3. sort those angle values.

Start with app/src/main/java/io/github/iyotetsuya/rectangledetection/utils/OpenCVHelper.java around line 164 and inspect how the current path-finding logic orders the four points. Compare it with the issue's center-point and angle-sorting approach; done means the detected rectangle points are ordered into correct paths, with behavior verified against representative detections.
