add no unbounded groups

[Tezra]

Nice plugin!

One thing that seems to be missing though is there is no rule that bans +, *, {1,} and {0,}, or in other words groups with no upper bound.

Not really a rule that should be on by default, but for any project that is not using heavy regex, it is good to put a reasonable upper bound on all groups to cap potential worst case, and the main thing I want to enforce on people less familiar with regex.

Thanks for the rule suggestion.

I'm welcome for someone to add that rule to this plugin.

There are already some rules to avoid the worst cases, so you might want to try using them in your projects.
