Incremental Snapshot

[rezabaram]

Why

We aim to provide incremental Cardano DB snapshots to allow clients to download and verify only the parts they are missing or interested in. This will make our current solution more useful by enabling users to download only the immutable files they lack, along with the relevant ledger state. For instance, a full node wallet user could sync their node in minutes or even seconds using Mithril.

What

Implement a new type of Mithril certified data which enables the retrieval and verification of a range of immutable files.
