Only enforce --fix rules for large codebase CI checks

[gehnmaisoda]

Hi! Thank you for creating and maintaining this wonderful gem.
I’m looking to introduce standard into a large codebase and want to run checks in CI.
However, I’d prefer to only enforce rules that can be automatically fixed using --fix, so that any rules requiring --fix-unsafely don’t fail the build.

I know generating a .standard_todo.yml might help, but it doesn’t quite match my intended workflow.
Is there a recommended way to achieve this? Any advice would be greatly appreciated.
Thanks again for all your work on this gem!
