fix dockerfile and add compose example (#5)

* Add docker-compose configuration for youtube-tldr service

* Add build.rs to Dockerfile

build.rs was not being copied into the Docker container. This file is responsible for compressing the static assets (creating the .gz files) that main.rs expects to include during compilation.
