Specify import require paths (continuation of #1941) (#1962)
* Add `.js` extension to source file imports

* Specify package `exports` in `package.json`

Specify package type as `commonjs` (It's good to be specific)

* Move all compiled scripts into `lib` directory

Remove ./number.js (You can use the compiled ones in `./lib/*`)

Tell node that the `esm` directory is type `module` and enable tree shaking.

Remove unused files from packages `files` property

* Allow importing of package.json

* Make library ESM first

* - Fix merge conflicts
- Refactor `bundleAny` into `defaultInstance.js` and `browserBundle.cjs`
- Refactor unit tests to be able to run with plain nodejs (no transpiling)
- Fix browser examples

* Fix browser and browserstack tests

* Fix running unit tests on Node 10 (which has no support for modules)

* Fix node.js examples (those are still commonjs)

* Remove the need for `browserBundle.cjs`

* Generate minified bundle only
