Scan QR code

[Hacklor]

As a user I can scan a QR code, so I can set up a connection to start using my identity

In order to use a digital identity the user needs to connect it to an application to actually be
able to use it. It needs to set up a connection (Telepath). It uses a QR code in order to do that.
The mobile application needs to have access to the camera and be able to scan and read a QR code and navigate to the URL that is in the QR code.

Acceptance criteria:

• Every time the camera is used, verify that user has given permission
• When no camera permission, create alert that permission is denied, direct user to give permission
• Ensure that we're consistent with iOS/Android way of asking permission
