🛠️ [TASK] : Cardano Blockchain integration API

[stevenj]

Summary

Define and create a Cardano Blockchain API for Hermes

Description

Interface to the Chain Follower crate based on Pallas.

Functionality to include:

1. Configuration for up to 4 networks, mainnet, preprod, preview, and a local test network.
   1. Reading config from disk, or setting it can be stubbed with working defaults until
      configuration file handling is done which is out of scope for this.
2. Start generating events for a blockchain on request.
3. Fetch a specific block from a blockchain on request.
4. Iterate a block and produce transactions.
5. Produce transition events and rollback events.
6. Ensure cardano events have proper interlocks so they are sent in the appropriate order/batches.
