feat: Move ID tests into their own crate with a CLI (#177)

* fix: ID tests not in correct directory

* refactor: Move game-id test logic into its own crate

* id-tests: Add CLI that reads JSON input

* id-tests: Update crate docs

* Remove node ID test

* id-tests: Don't try to parse unneeded info

* id-tests: Enable cli feature by default
