Added examples to validate peerjs in node

- Added dthe examples dir with a simple echo server and client setup
- Changed the serialization of the data from Binary to JSON because
Binary refuses to work
    - It would have been nice to get Binary working though, I will have
      to look into it more
- Removed the contents of `footer_patch.js` because they were not having
the desired effect
- Added the `index.js` as the main entry point of the module to prevent
users from having to do `require('node-peerjs').default` because
`parcel` does not package for nodejs right now
