Need to adjust to 0xMiden/crypto#900 (review)

It seems a bit silly to migrate this one out of the crypto repo while it's still undergoing some evolutionary changes with the API (e.g. 0xMiden/crypto#880). Is there a particular rush to do it?

[drahnr]

I wouldn't call it rush, but I see a need to complete this to be able to fix bugs / iterater rather quickly compared to propagating it through protocol from the node perspective.

What is left that is significantly breaking public API from your pov, today?

There is also another effect of starting the work early - figure out what needs to be exposed publicly in addition to the current API surface of crypto.

I don't think I have any breaking changes planned. It's more that keeping a copy of the persistent backend in crypto for now is valuable for getting the interface and design of these things right.
