Think of a way to summarise the results better

Is your feature request related to a problem? Please describe

At the moment we get the results like a list of files with the failed rules. We could, for example, prefer to have a list of failed rules with the associated files. Or something else (?)

Describe the solution you'd like

Have no clear solution for this yet, but hopefully this issue will spark some discussion on how to achieve better results.

I can think of, at least:

1. by_ruleset: by ruleset, then rule, then file
2. by_rule: by rule, then file
3. by_file: by file
4. (eventually summarise by_category) we're thinking about making rulesets the categories
5. plain, which would make it easy to open an editor on the obtained results (?)
   5.1. results can/should be something like {file}:{line}:{column} - <rule_name> (<rule_md>)
