Subject: [PATCH 2/2] [patch] use binary encoding function that does not
 overflow

If the qr codes get too big (in total file size), then the current function will blow up. This one works better, tested manually by updating the dist/build.js, and updating example.html to point to that instead of the production cdn hosted websdk
