Custom grid from image

--map followed by an image filename, generate grid from image. White pixels (i.e rgba[255, 255, 255, 255]) are dead cells, any other colours will be treated as living cells. Image file must match window height and width.

For example: ./game_of_life --map example_map.png

Update speed

For example: ./game_of_life --ms 30

Cell size
