Pre-commit integration

[jrottenberg]

Expected Behaviour

csvlint should have a .pre-commit-hooks.yaml to allow user to leverage pre-commit and run csvlint automatically on commit

Desired Behaviour

pre-commit config file and updated readme for usage

https://github.com/belminf/pre-commit-chef/blob/master/.pre-commit-hooks.yaml for example is very similar (in spirit) :

• look only for specific type of files that are changed by the commit
• installed via gemspec (https://pre-commit.com/index.html#ruby)
• exit code to pass or not the hook

If there's interest I wouldn't mind implementing the change, but I'd rather make sure you are on board before implementing it.
