User calib fixes (#1114)

* Updated user calib boards to be compatible with OpenCV <=4.6.0 (legacy patterns) * Added minMarkers parameter to Charuco board detection to increase the number of detected corners also in visualization for the user. This change mirrors what has been done for actual calibration in depthai_calibration so the visuals and actual detection are now identical.
