FR: webcam support

[thibaultmol]

Hi, it would be nice if the app also had an option to the use the camera or webcam to scan qr codes

Hi. Yes I agree. I was planning to add that but it turned out a bit more complicated because dealing with native APIs across the thousands of configurations on Linux is a nightmare. I'm currently very busy with work but I will review any PRs.

I would also appreciate webcam support, as a workaround on Linux I start Cheese and then take the screenshot. Works but a step too much.

For phones AFAIK all modern phone cameras also have native QR code recognition, so that there maybe it isn't so much of a must have feature.
