Support for gRPC streaming in Auraescript

[JeroenSoeters]

Right now, we don't support streaming in the TypeScript API, it would be nice if we would.

Will probably need this: https://docs.rs/deno_core/0.170.0/deno_core/trait.Resource.html#

This may go against the goals of the project, and I may be missing a key advantage to having Rust be the glue for the gRPC interactions, but it may be worth looking at using a Deno compatible gRPC library for JavaScript, and then wrapping those in the predefined API functions.

It may also be useful for a developer who wants to utilize the "vanilla" gRPC interaction functions in JavaScript (maybe to access unstable features? or just want to for 🤷🏻‍♂️ ).

I've been using this library to write gRPC clients in Deno apps: https://github.com/bufbuild/protobuf-es

EDIT:

ES Protobuf doesn't generate service definitions at this time, so may not be the best choice.
