Cross-runtime modules with dnt

Library authors may want to make their Deno modules available to Node.js users. This is possible by using the dnt build tool.

dnt allows you to develop your Deno module mostly as-is and use a single Deno script to build, type check, and test an npm package in an output directory. Once built, you only need to npm publish the output directory to distribute it to Node.js users.
