[Lightning-dev] RouteBoost: Adding 'r=' fields to BOLT 11 invoices to flag capacity

Hi all,

        I'm considering a change to c-lightning, where `invoice` would
automatically append an 'r' field for a channel which has sufficient
*incoming* capacity for the amount (using a weighted probability across
our peers).

         This isn't quite what 'r' was for, but it would be a useful
hint for payment routing and also potentially for establishing an
initial channel.  This is an issue for the Blockstream Store which
deliberately doesn't advertize an address any more to avoid
centralization.

Thoughts welcome!
Rusty.
