improve messaging for calibration issues with checkerboard #241
Description
current message: "The checkerboard was not detected by at least one camera. Verify your setup and try again. Visit https://www.opencap.ai/best-pratices to learn more about camera calibration and https://www.opencap.ai/troubleshooting for potential causes for a failed calibration."
messaging could be improved since this might be confusing for someone who put in the wrong number of rows/columns vs the checkerboard could not be seen by the cameras. perhaps something like "Error in calibration setup. Ensure the checkerboard can be seen by all cameras, and verify your checkerboard parameters.
