For each pixel, calculate the average of the r. g. b values of the color image, and set all three r, g. b values to this average. Use the same main program to test your new function. Write a setColor function that expects two arguements: an image and an RGB tuple containing three integers. The setColor function should set every pixel in the image to the RGB tuple color. Test the setColor function from an interactive main program that creates a blank image that is 200 pixels wide by 100 pixels tall, allows the user to enter three integers for the RGB values, prints the prompt "Close the image window to continue", calls setColor with the image and the user specified color tuple, and draws the image
