Cannon flash animation looks a bit off #304

The animation of the cannon flash in the previous version looks a little off. The graphic grows at a constant rate and then instantly disappears. We can make it look more like a real cannon flash by adjusting the lerping.

I updated the animation using an ease-out function to make it look more like a real muzzle flash - link

@matthew-blackman the updated flash looks nice. It's an improvement over the original animation -- still whimsical and functional, but less harsh/distracting. I think it's a keeper.

I took a few quick clips in case we ever want to compare it side-by-side in the future.
