#7 name resolution

Resolves #7

Brief description

Name resolution already works. All we need is a way to change resolution depending on network. Ideally, we would call the nameservice, but Koilib does not have an abstract for that. Instead, we can rely on env vars and change config accordingly.

If our ABI works, why can't we use the name service?

[mvandeberg]

The name service should be looked up via invoke_system_call, not by calling the contract address directly. It can be done, but is it worth the dev work to do it right now?
