DeployERC20 functionality for wallet and wallet_address

[rohan-agarwal-coinbase]

What changed? Why?

• Updated the smart_contract.ts with the SmartContract model with the appropriate getters and the ability to sign/broadcast/wait on it
• Created new types in types.ts to wrap the underlying SmartContractTypeandSmartContractOptions, and to define theSmartContractAPIClient` functions
• Renamed the existing smartContract API client to contractEvent in coinbase.ts
• Added new smartContract API Client which is constructed from SmartContractsApiFactory
• Updated wallet_address.ts with the new deployToken function
• Updated wallet.ts with the new deployToken function'
• Updated tests, pretty much copying the same pattern as contract_invocation tests

Testing

npm run test succeeds. I also deployed a new token through the local cdp-service
