 - Add `AccountUtils` class to help with account serialization and deserialization
 - Add `SingleKeySigner` interface which adds the ability to get the `AnyPublicKey` from a `SingleKeyAccount`
 - We now throw an error earlier when you try to use the faucet with testnet or mainnet, rather than letting the call happen and then fail later.
