Request: Make invoice macroon available

[bitrequest]

The invoice macaroon is a safe way to use for connecting to bitrequest.io point of sale and potentially other lightning applications that need limited acces.
As a bonus, a QR code of the lndconnect URL would make it a lot more convenient to connect from mobile devices.

Any plans to implement this?
It would make connecting your node to bitrequest.github.io (And other apps) super easy and safe.
