feat: next round animation

• Closes #69
• Update sprite by adding the white maze next to the blue one.

You can look at the comment https://github.com/Livl-Corporation/livl-pacman/issues/69#issuecomment-1596050670 to see how it should look like as the Arcade Game: Pac-Man (1980 Namco) video.

Here is a presentation of my work

Maybe I can add a new timer at the end of the next round animation to display for 1 second a black screen for a better transition ? What do you think ? (look at the https://github.com/Livl-Corporation/livl-pacman/issues/69#issuecomment-1596050670 to see what I mean)
