Remove remote CDN dependency for the Barcode Detection Polyfill

[leifriksheim]

For ADAM Connect we are using this polyfill to enable QR code reading for mobile: https://github.com/undecaf/barcode-detector-polyfill

This polyfill fetches a CDN remotely for the WASM file. This makes ADAM Connect not usable in Codesandbox, jsfiddle etc. Also it wouldn't work offline, so we should find a way to include the WASM file directly.
