Today We Did
1. Create a file called wall_explosion.py for the WallExplosion class which:
a. uses all the images in assets/Bricks to make an animation (have something like tank's get_next_image)
b. once you've shown all the images, call self.kill()
2. In main, create the wall_explosion_group.
3. Add a collision between the bullet and the wall. Both should disappear when they collide, but create a new
WallExplosion in the place of the wall.
