QR code generator for phone control

For presenters who use the phone link slide advancer, cut out the need to send a link to a phone (via number, email, whatsapp etc) by allowing the phone to access the link via QR (one that has a copy function for embedding into slides would be useful)

All it takes is using the camera on your phone, and clicking the link

It's not uncommon for presenters being uncomfortable sending over their number to some tech womble in another country (and rightfully so) so this would also circumvent that issue

I am aware you can generate QR's easily via a browser, but this just cuts the middleman of having to generate 10+ QR's per event, and potentially sending the wrong code
