[Feature Request] Add a QR option to connect a Bitcoin node

[4rkad]

Most node implementations in Bitcoin have the option to connect via QR to the electrum server (electrs/fulcrum), this protects you from having to share credentials through messaging applications if you want to connect the node to the mobile. Having a QR viewer to connect directly would be perfect.

@4rkad can you please provide me an example QR for this? That would help make this quicker :)
