This updates our `tsconfig.json` so it emits our JavaScript files as well as type checking them. We compile into `./lib` which we then ship in our npm package. The source code has moved from `./lib` into `./src`. Because the `src/` directory is exclusively JS files, this change is a no-op in terms of code functionality but is the first step towards being able to replace `src/X.js` with `src/X.ts` in a way that allows us to migrate incrementally. The `lib` directory is gitignored, and the `src` directory is npmignored. On `npm publish` we will now run `npm run tsc` in order to generate the outputted code.
