Add golang client, server and dart client support

[vetcher]

I'm in search for service schema definitions and considering to choose your ecosystem openrpc. My stack is golang backend with microservices (so go <-> go interaction important too) and flutter mobile apps. Right now this tool supports only ts and rust as I can see.

Could you help me understand:

1. How can I help you add go client, go server and dart client templates? I'm already have all generators based on https://github.com/semrush/zenrpc and SMD schema, but I dont know ts nor js at all.
2. Why I need to install node.js and keep it as a dependency for my project? I propose to create separate repos for each language, like it does in OpenAPI (aka swagger) or Graphql ecosystems and write generator for each on their own languages. So it would be easier for me to help add more languages. OR allow to feed templates to your tool on fly (at execution time), protoc and protoc-gen-* (grpc-ecosystem) service generators works exactly like that (https://github.com/grpc-ecosystem/grpc-gateway) and distribute core generator in binary form.

@vetcher if you are using golang there is this library to generate the openrpc document from your code: https://github.com/etclabscore/go-openrpc-reflect

Also the advanced section of the webinar is all about go-openrpc-reflect and generating documents from code: https://open-rpc.org/webinar/

as for client generation, the language its written in is nodejs so you definitely need nodejs, dont think there will ever be a way to get away from that, just as swagger codegen requires Java. That being said, we do have plans to move each language to its own repo to be able to be composed within this repo, and be able to provide external templates like you mentioned.

Golang client support and flutter would definitely be good additions to the current generator.

As for binaries, I've played around with https://github.com/nexe/nexe but it produces quite a big binary since it has to include all of nodejs.

@vetcher Work has been started to get golang clients done. We have the generated typings already, we just need to chose a client and get the template together. If there is someone wanting to put up funding to get that done, it will happen a lot faster :).

Passing in templates is an interesting pattern and something to consider, thank you.
