Tonic include_proto utilities

A crate to make using tonic::include_proto less painful.

namespaced!

This macro invokes the macro tonic::include_proto for multiple protobuf packages and each of them are placed in the correct namespace.

Example

The code: rust tonic_include_proto::namespaced!("x.y", "x.z");

is equivalent to: rust mod x { mod y { tonic::include_proto!("x.y"); } mod z { tonic::include_proto!("x.z"); } }
