I have a `buf.yaml` file in the repo, but it only lists some of the proto files/dirs (for unrelated reasons). I'd like to use the `buf_format` Bazel rule to format all the proto files in the repo, not only what is listed in `buf.yaml`. There is currently no way to do what I'd like to do. Would be good to make it possible to either specify a custom config or ignore the existing config (my preferred option). Or maybe both. Thank you!
