Add LUD-22: Payee Data. #252

This is the payee-side equivalent of LUD-18. It gives the opportunity for the payer to request that the payee provide identitifying information before the payment is made. This allows the sending WALLET to show information about the receiver in order to allow the payer to verify that they are paying the correct entity. This also gives the opportunity for the payee to authorize themselves via a challenge-response mechanism to provide some assurance that SERVICE has not been compromised.

This document is largely copied from LUD-18 with some minor tweaks and additional context to make it make sense in the opposite direction.

FYI this is now live in UMA v1 and VASPs are rolling it out. Xapo, Ripio, and Bitnob are upgraded and several more are on the way.
