Provide a basic conformance test suite

[ghost]

Details

• Write conformance test driver using Agda spec as an oracle
• Define interesting scenarios and relevant generators
  • Requires defining interesting properties we want to assert of the implementations
  • Focus on adversarial conditions and scenarios
• provide needed drivers for both Haskell and Rust prototypes/simulators
• Explore possible approach to conformance testing for Leios #42

Definition of Done

We can run tests against prototypes and demonstrate they respect expected properties.

The branch conformance-testing provides a basic setup for conformance testing using quickcheck-dynamic. We intend to use the executable specification from #52 as model to test against.
