v0 Dart client generation

[austinmilt]

This PR adds Dart client code generation. It requires a single import into the client's codebase (documented in the README)

This version includes

• client code generation (see base directory starting in main.go.tmpl)
• services interface generation for mocking in tests (types.go.tmpl)
• test validation against the test webrpc schema (tests/scripts/test.sh and tests/test/reference_test.dart)
• test validation against an additional webrpc schema (tests/test/custom_test.dart)
• CI test automation (.github/workflows/ci.yml)
• an example Flutter client app with a Go backend (_examples/flutter-go/)

Note this version ignores wide/large number truncation that occurs in web environments (i.e. Flutter web) (see webrpc/webrpc#283)

LGTM. I think this is excellent!

@austinmilt What a great contribution to the webrpc project. Thank you! 🎉

If you agree, I can get this into webrpc binary as an officially supported client.

I've never worked with Dart, so I won't be able to run/test this myself today.. but the tests suite looks very robust 👍

I would love to see this officially supported. Just FYI this version is what I'd consider a minimal implementation

• doesnt support metadata generally
• types cant be compared for deep equality
• doesnt attempt to define or return default values

@austinmilt it's a very great start :) Feel free to create issues for what you think is missing 👍

I made some issues but will likely wait to implement anything until/unless folks end up using the library (including myself :D) .
