 Pull a github user's contribution graph.
 Make it a snake Game, generate a snake path where the cells get eaten in an orderly fashion.

 Generate a [gif](https://github.com/Platane/snk/raw/output/github-contribution-grid-snake.gif) or [svg](https://github.com/Platane/snk/raw/output/github-contribution-grid-snake.svg) image.
