Add a way to Scan a QR Code that contain a Gziped JSON

[jeremi]

This would be available only through another app that calls using intent.
For QR Code scanning, we should be able to have those options:

• gzipped (true or false)
• json (true or false)
• Json path (to get 1 value in a json file)

return in the intent:

• qr_code_text
• qr_code_json_value (the target value of the json path)

Lib:
