* Add a spec test fuzzer for Config This commit adds a new fuzzer which is intended to run on oss-fuzz. This fuzzer creates and arbitrary `Config` which *should* pass spec tests and then asserts that it does so. The goal here is to weed out any accidental bugs in global configuration which could cause non-spec-compliant behavior. * Move implementation to `fuzzing` crate
