feat: replace JS SDK generator with ts-proto generator

[jonas-jonas]

This replaces the existing generators with https://github.com/stephenh/ts-proto, which can generate more user friendly code. It also allows generating client for the nice-grpc framework.

BREAKING CHANGE: The structure of the JS SDK had to be changed to match the new generated code.

I'm closing these PRs as we never got it to work. This problem hasn't come up in the past few months so I think it's on the bench for now :D
