Formatted mdlr.yml file

[MiMiMeowMeow]

I know we are suppose to use the CLI to edit the yaml file but it sometimes it's easier just to go in with an editor and change a few things. Is it possible to configure the writer to format a little better to so we can more easily see which module we are editing.

Thanks

@MiMiMeowMeow Definitely feel your pain editing large mdlr.yml files! We're this library for the YAML stuff and unfortunately (even with the flow flag on the modules property) we're not able to get the pretty output. AFAIK there aren't any other production-ready YAML libs in Go. Nonetheless, let's definitely keep this open and we can consider some potential implementation options soon. Thanks!
