Barcode rendering and decoding

1. Install extension and required packages: npm i @zxing/browser:0.0.8 @zxing/library:^0.18.5 webrtc-adapter
2. Import Javascript:
   • import { default as Zxing } from 'js/components/zxing.js';
   • Zxing.go();
3. Create a template like the one in Resources/Private/Templates/BarcodeGenerator/Form.html (SET THE ID`S OF THE ELEMENTS!!)
4. Pass an optional handler to the go method (for an example, look into Resources/Private/JavaScript/zxing.js onDetected(result))
