Automatic code formatting?

I tried searching on the issues page, but couldn't find anyone who mentioned it, so I figure I would.

Has it been considered to add an automatic code formatter and guidelines in the contributing and a formatter configuration to the repository? I know I have had problems in the past where I've had to disable my editor's auto-formatting and manually adjust code format when working in the repository. Perhaps something like `clang-format` or a suitable alternative? At this point, it would be a pretty massive `git diff` that would destroy the blame, so it may be too late if preservation is a priority.

This is what sparked my question, as a CI/CD checker would prevent it: https://github.com/facebook/zstd/pull/3917#discussion_r1503239971

Obviously, this project has done well without it, so "no" is a perfectly acceptable answer as well 🙂
