Add a border to sl-qr-code

[OneCardDev]

QR codes usually require a clear border around them to help the reader see the edge of the code - can this be implemented?

This can be achieved with CSS, if that helps.

Thanks - but that won't add the border to the QR image if someone wants to download it and use it elsewhere.
