Un-require previous rule exclusion

[paulo-ferraz-oliveira]

Is your feature request related to a problem? Please describe.

I'm always frustrated when, after fixing an issue that hank was complaining about, and for which I created an exclusion rule, which I finally do a fix (e.g. I start using that argument that I wasn't), and hank doesn't warn me that the previous exclusion is not required anymore.

Describe the solution you'd like

Hank telling me about unused exclusions.

Describe alternatives you've considered

I've only ever considered removing an exclusion, running it again, and figuring out if it's complaining, but that doesn't seem very good as a process.

Additional Context

I know this might not be easy to implement, but am opening it as a feature request in case the maintainers hadn't discussed it yet.

Well... The unused exclusion is, in fact, Oxbow Code and therefore it could be detected by Hank. 😎 We might just need a new rule for this. 🤔

I like the way you think here. And there, too.

Nice, I like it!
