RFC -doc fix to address mimblewimble/grin-wallet#663 #10
Description
Fixes Issue 663 reported by Renzokuken. The current RFC for grin SlatepackAddress derivation + the output printed by grin-wallet is confusing since the derivation path shown is for output keys and not for the SlatepackAddress.
This PR fixes this problem at least on the documentation level. Further fixes in grin-wallet itself might further address this issue:
