Add option to clear left, then right, or right, then left

[evanrich]

The current animation only goes one direction, add an option so that it clears one way, then comes back the opposite direction. Maybe a -ltr for left to right languages or -rtl option (for those who's languages go right to left, etc.) https://gifdb.com/images/high/pacman-game-left-and-right-i9zhl3ky1ftgwj6s.gif

Thank you for the comment. That's a good idea; I'll consider adding it as an option.
