Migrate from jsQR to qr-scanner for full barcode support.

[juliansteenbakker]

On web, jsQR is limited to QR codes only. We should migrate to qr-scanner or something similar to support other barcodes aswell.

Hi there!
Quick question, is there a specific reason that the StreamController in the mobile_scanner_web_plugin.dart file is not a broadcast StreamController. I'm having problems using the QR reader more than once in the same web app. Thanks in advance for your response.

The controller is since PR #94 a broadcast Streamcontroller

qr-scanner (https://github.com/nimiq/qr-scanner) is also limited to QR codes

It looks like this implementation has a better support for barcodes and cross platform browwsers.

Maybe I can do this one day; I wrote the initial implementation in juliuscanute/qr_code_scanner#306 too and actually promised to still improve it.

I have look into this library and build simple_barcode_scanner but it is not promising as you can see the issue here

If the underlying problem is specifically that It can't read EAN-13 barcodes with leading Zero mebjas/html5-qrcode#361 (comment) I think it's very promising, I would argue that it's maybe a better implementation than the current one.
