feat!: new exports ContractClient and Rpc

- `SorobanRpc` renamed `Rpc`
- New main export `ContractClient`
- `ContractSpec` now available at `ContractClient.Spec`
- Also includes other supporting classes, functions, and types:
  - `ContractClient.AssembledTransaction`
  - `ContractClient.ClientOptions`
  - etc

These are also (maybe) available at top-level named export, if your
tooling supports the `exports` declaration:

    import { ClientOptions, AssembledTransaction } from 'stellar-sdk/Contract'
