Lack of Implementations of Vouch

There is a lack of implementations of vouch sending, which has resulted in a lack of receiving vouch implementations.

The reason for this is that the protocol lacks suggestions on how one might start generating vouch URLs in a concrete manner, see #1

Specifically for receiving, the exact parameters may vary by implementation, but suggesting methodology would increase adoption

Start with issue #1 and the Vouch specification linked in the repository description. Define concrete guidance for generating vouch URLs and methodology for receiving vouches, while documenting which parameters may vary between implementations. Done means the specification offers actionable implementation guidance that can support both sending and receiving adopters.
