feat: add cli package for quick installation

This will just install the package and will unload the burden of
npx-ing @wpackio/scripts and then installing it again.

+This package has the same `npm scripts` as this monorepo. These should be run
+using `lerna run <script>`. More information can be found under [CONTRIBUTION.md](../../CONTRIBUTION.md).
+
+-   `build`: Use babel to build for nodejs 8.6+. Files inside `src` are compiled and put under `lib`. All type definitions are stripped and individual type declaration files are created.
+-   `prepare`: Run `build` after `yarn` and before `publish`.
+-   `lint`: Lint all files using tslint.
+-   `test`: Run tests on files using jest.
