Screenshot QR examples missing

[1oglop1]

Hi,
since this project is about creating QR codes it would be nice to see the some real results in images.

Thanks for your report. This lib is just a thin layer which emulates the API of other QR code generators and uses the main project Segno. I think I won't add images here, because this project is all about adapting Segno to other APIs. But maybe some images in Segno's documentation would be nice.

I added an issue to the main project, see #44
