a41cbbdc99 findChessboardCornersSB: performance + support for full FOV boards with markers 
Changes:

* UMat for blur + rotate resulting in a speedup of around 2X on an i7
* support for boards larger than specified allowing to cover full FOV
* support for markers moving the origin into the center of the board
* increase detection accuracy

The main change is for supporting boards that are larger than the FOV of
the camera and have their origin in the board center. This allows
building OEM calibration targets similar to the one from intel real
sense utilizing corner points as close as possible to the image border.

* Handle det == 0 in findCircle3pts.

Issue 16051 shows a case where findCircle3pts returns NaN for the
center coordinates and radius due to dividing by a determinant of 0. In
this case, the points are colinear, so the longest distance between any
2 points is the diameter of the minimum enclosing circle.

* imgproc(test): update test checks for minEnclosingCircle()

* imgproc: fix handling of special cases in minEnclosingCircle()
