Rudimentary code-completion in transifex/api

How to test:

1. Checkout this branch
2. `cd <path-to-repo>/packages/api`
3. `npm run build`
4. `npm link`
5. `cd <path-to-empty-folder`
6. `npm link @transifex/api`
7. Open `index.js` in vscode and type:

   ```javascript
   const { transifexApi } = require('@transifex/api');
   transifexApi.setup({ auth: 'XXX' });
   async function main() {
     const page = transifexApi.Organization.list();
     await page.fetch();
     console.log(page.data);
   }
   main();
   ```

   While observing what auto-completions the editor offers. After
   `transifexApi.` the editor should offer all API resource types
   registered with the SDK.
