Add pacman contribution graph game

[abozanona]

Is your feature request related to a problem? Please describe.
It would be great to provide users with more creative and fun ways to display their contribution activity.

Describe the solution you'd like
I suggest adding support for pacman-contribution-graph, which turns the contribution graph into a Pac-Man style game. This could be integrated as an additional option for users to include in their profile, similar to the other widgets and stats already supported.

Describe alternatives you've considered
I didn't see anything similar.

Additional context
Here’s the project link again: pacman-contribution-graph

I’d like to open a discussion on the best way to integrate it into github-profilinator, and discuss the best approach to do it.
