feat(rpc): add rpc_name flag for generating rpc service code

- Add --rpc_name flag to set the RPC service name
- Update configuration file and main file generation to use the specified service name
- Modify README to include new flag description and usage examples
- Enhance support for generating code from multiple proto files within the same service
