Add extra type-safety to ensure that all predicate failures have roundtrip tests

[Soupstraw]

Description

This PR adds the RuleListEra typeclass, which has an associated type level list with all the (fallible) rules in that era. This gives us a closed world view of the rules and that makes it easier to write tests that iterate over each rule. See roundTripAllPredicateFailures for an example.

resolves #3866

This is looking great!!! 😃

This looks great. Exactly what I envisioned. However, we need the same testing for all previous eras as well not just Conway.

Beautiful!
