disable automatic formatting

[futurepaul]

I'd love it if this project adopted rustfmt but in the meantime I think it's a nicer first experience to not accidentally have my editor format the code on save (default behavior, at least on vs code + rust analyzer) and then I need to remember to disable rustfmt for this specific project. Rustfmt has a flag for this: https://rust-lang.github.io/rustfmt/?version=v1.5.1&search=#disable_all_formatting.

There's also an "ignore" flag but that didn't work when I tried it.

Thanks! It's indeed annoying when using format-on-save and such.
