Interest in a Dockerfile?

Hey, thanks for the great tool!

We internally created a little Dockerfile to ease the distribution and usage of pup. Would you be interested in a pull request to add a Dockerfile, so that there might be an official image on the Docker Hub?

I would be. Create a PR!

See #128 for a somewhat simple, yet useful Dockerfile :)
