Building container images for Deno, without Docker

./build.sh builds example.js using deno compile, then appends it on top of a default distroless base image, and makes the example executable the image's entrypoint, using crane.

It does all this without a Dockerfile, without invoking docker build, and without requiring a container runtime.

./run.sh runs ./build.sh then runs the resulting image using docker run. Only this step requires a container runtime.

./build.sh takes two optional positional args: ./build.sh [image-to-build] [base-image]
