take aways from offline convo:

1. add extend method to ISmartContractAccount with impl in BaseSmartContractAccount -- should be copy paste impl from Provider since it's the same concept
2. Update the loupe decorator to just take in the account
3. remove extendWithLoupe method from builder and dynamic class
4. call account.extend(accountLoupeDecorator) in the multi-owner-account.ts builder method
