Add QR code scanning to "Add new repository" containing all details of a repo

• Device OS and version: Android 9
• Device model/manufacturer: Model and version undisclosed for privacy
• F-Droid version (in the About screen): F-Droid 1.7.1

What did you do? (clear steps if possible)

• Navigated to Settings
• Clicked on Repositories
• Clicked on +

What did you expect to see?

Ability to scan QR code which will contain both repository and fingerprint. This would be great to have this to have ability to add independent, small repositories hosted individually by developers.

What did you see instead?

I see a simple dialog to add URL and fingerprint. As this requires multiple navigations back and forth, copying and pasting details it makes it difficult to add a new repository.
