Write a program that creates a green 'T' logo for Thomas Hunter on a 30x30 grid.

The grading script is expecting:

• The file to be saved as: logo.png.
• The grid to be 30 x 30.
• The 'T' to be 0% red, 100% green, and 0% blue. The top part of the 'T' should be the top third of the image and the bottom part of the 'T' should be the center third of the image.
• The remaining pixels in the image should be white (100% red, 100% green, and 100% blue).
