OpenCV Grayscale Thresholding Function

This function applies thresholding to an image using the cv2.threshold method from the OpenCV library. It first converts the image to grayscale, then applies the thresholding operation, which sets pixels with grayscale values above or below specified thresholds to either the maximum value (255) or the minimum value (0).
