OpenMV Camera Blob Detection and UART Communication

The code provided sets up a camera sensor, initializes a UART communication, and continuously captures images from the camera. It then searches for blobs with a specific color threshold and finds the largest blob. The code draws a rectangle around the largest blob and sends the centroid coordinates of the blob over UART. The centroid coordinates are also printed to the console.\n\nPlease note that there are a few places where you need to modify the code according to your requirements. These include setting the appropriate image size, adjusting the color threshold values, and modifying the code to draw the rectangle in the desired color and location.
