CV Stereo Calibration From CSV

Reads per-image stereo calibration from CSV files (e.g. StereoGeo-CARLA). Computes camera intrinsics K from vertical FOV (pinhole model, no distortion). Returns K, dist (zeros), R, T ready for stereoRectify. CSV columns — left: image_name, width, height, roll, pitch, vfov. Right: same + R_00..R_22, t_0..t_2. Found=false if the image name is not in both CSVs.
