refactor: separate CJS and ES bundles to reduce bundle size

BREAKING CHANGE:
* Entry points have changed. This will affect UMD consumers. Now the file name is `workfront-api.umd.js` and `workfront-api.umd.min.js` respectfully.
* For Node users, the api class name has been changed to `NodeApi`. This is to prevent typing ambiguities.
```
const Workfront = require('workfront-api')
const api = new Workfront.NodeApi({/*...*/})
```
