Splice.Ans.AmuletConversionRateFeed

Templates to communicate amulet conversion rates. This does not fit a narrow interpretation of “Amulet Name Service”, but it fits very well if we widen the role of the ANS to serve as a store for public data of high-value to network participants. Evolving ANS in this direction is a long-standing plan.
