Example of distributing Protobuf files from centralized repository to sub packages like Golang, Python, Rust, Node.js while maintain their each languages / frameworks workflow and structure of projects. Each sub-repository can have their own publishing mechanism like go-releaser, or bumpp for Node.js.
