Could please use Go modules to manage dependencies?

The release of Go v1.16, which sets GO111MODULE env to on by default (ref: https://golang.org/doc/go1.16#go-command), leads to build failure of Homebrew formula buildifier and buildozer. Thus they disable them for now in PR Homebrew/homebrew-core#71330

If to use Go modules to manage dependencies, it'll be great for downstreams (eg. Homebrew) to build and install them.

I have attempted to file a PR for this but build failed #959

So the idea of Go modules is when you make a breaking API change, you increase the major version.
At this time, we have not made any breaking changes that I am aware of, so even though we are version 4.0.0 it isn't really a Go 'v4' implying a 3rd breaking API change.

So I think all we need here is a go.mod and go.sum file to make this work?

Yeah, the idea is to make builds reproducible for downstream that does not use Bazel.

You guys should release a new version so that downstream (eg. Homebrew) can use the new version commit to re-enable, build and install buildifier and buildozer.
