Verify our Rust CBOR error deserializer against Haskell's serializer

[michalrus]

In a huddle with @ginnun, we had an idea. 💡

Since it would be hard to generate all possible errors by constructing invalid transactions with cardano-cli conway transaction build-raw, why not just:

1. purely construct only the errors in Haskell,
2. serialize them there,
3. and then try to deserialize them with our Rust code,
4. and compare both representations?

This could even be done quite dynamically. They may even already have QuickCheck random generators for the errors, that we could reuse.

The representations should be the same for all errors, and then after running thousands of such property checks, we can be reasonably sure that we are returning the same errors as cardano-submit-api.

We could also use the cardano-api-submit error serializer (CBOR → ADT → JSON), to compare if we are constructing the JSONs in exactly the same way, based on the deserialized ADT.

To run this on CI, we’ll need #34 first, but @michalrus can already start working on this one locally.

Required by:

• Make transaction rejection error (node) same as blockfrost submit error #19

I'm going to reassign this to @ginnun after:

• feat: use testgen-hs for deserializing ApplyTxErrors #93
• feat: testgen-hs – random Haskell CBOR error generator #71

The Haskell tool is available from our devshell to test against.
