Thank you so much for your hard work on this! Weird github didn't email me about an open PR.

A couple of pieces of feedback before I'd feel comfortable merging this:

• Fix merge conflicts
• Squash commits down into 1 commit for this PR
• It looks like some of your rules deleted some validation rules. Can you please make sure all of your rules match all of the rules from https://ntsi.com/drivers-license-format/

[Zoooook]

Looks like the merge conflicts are due to your recent overhaul of the system. I last touched this a year and a half ago for a project at work, and I'm not terribly interested in it anymore. All I did was clean up the regex in some cases and change the rules in other cases to comply with the 2014 MVR Access and Decoder Digest, as noted in my commit messages.

I would assume that our 2 sources for validation rules are in conflict in some cases. You're welcome to verify those rules by looking through my unit tests. I would however question the authoritativeness of NTSI.

It may be better to just leave my branch as a fork; my main interest was getting a groovy version that complied with the source we had to use at work. Updating the regex in your format was just a bonus. Feel free to steal my regex, or not, as you see fit.
