Make a bundle for the https://github.com/stdupp/goasciiart tool. Use it to convert cute pictures of gophers into ASCII art when you install the bundle.

Here are some hints so that you can try to solve it in your own way. For the full solution, see the asciiart directory in the workshop materials.

• A good base image for go is golang:latest.
• You need to run porter build after modifying the Dockerfile.tmpl to rebuild your invocation image to pick up your changes.
• Don't forget to copy your images into your invocation image to /cnab/app/.
• The command to run is goasciiart -p=gopher.png -w=100.
