Cardano template PoC

[SebastienGllmt]

This adds a template which allows easy testing of Cardano integration by (similar to our hardhat setup) allow spinning up a custom Cardano network for testing purposes

Spinning up this custom network is done using yaci-devkit, and once it's spun up an initialization script is run using CML

Tasks remaining:

• [ ] https://github.com/dcSpark/carp/issues/189
• [ ] https://github.com/dcSpark/carp/issues/188
• [ ] https://github.com/dcSpark/carp/pull/187
• [ ] https://github.com/dcSpark/carp/issues/190
• [ ] (optional) remove need for user to manually setup yaci (https://github.com/bloxbean/yaci-devkit/issues/28)
• [ ] Replace the 4 yaci steps (start, yaci-cli, create-node, start) with a single step in cardano:start (note: this my be helped by https://github.com/bloxbean/yaci-devkit/blob/boot_upgrade/devkit.sh)
• [ ] Decide if we need the secrets fields in the Cardano docker-compose.yml
• [ ] Bump Carp docker images (docker image for Carp is updated automatically when pushing to main / making releases on Github)
• [ ] README to properly document how the template works (and possible add to the Paima docs)
• [ ] Update frontend so that it does something interesting with Cardano (ideally leveraging all our Cardano primitives)
