Exposes what I consider a good public API from the `internal/formatter` package. Having a go-native formatter is an awesome thing, especially because it allows shipping the formatter as part of other projects. It's also fair to keep the formatter's code in `internal`, yet third party projects should have a way to use relevant parts of it.
