Make CleverCSV a pre-commit hook

Would you consider making CleverCSV a pre-commit hook, by adding a .pre-commit-hooks.yaml file to your repository? This would allow people to have csv files in their repositories to automatically check them whenever they want to commit them.

The only thing missing to make it work is, as I understand:

• An option to overwrite the input file instead of printing to STDOUT (I think this could be a flag, like --in-place)
• The possibility of clevercsv to accept a list of file arguments to process.
• (Probably implemented already) A different exit status whether the input file was altered (!=0) or not (=0).

I can file a PR for the .pre-commit-hooks.yaml, if you agree (after the above points are implemented).

Thanks for your consideration!

The dummy package has a test suite to verify the hook works, but I’d appreciate it if you could double check 😃

Can confirm that it works for me without problems.

Thanks a lot for all your effort!

(Not closing as merging of #30 will do so)

Cool, I can confirm that your repo works!

I’m trying to think about how to set this up so it isn’t a lot of effort to maintain going forward. I think the setup.py of the mirror repo can be simplified to pull the version info from the .version file (similar to what we do in this repo), and then I can add a bash script or so to update that .version file and do the git tag whenever I do a new release of CleverCSV.

I’ll pick this back up tomorrow, thanks for your help!
