Missing Counter Rollover Mechanism in the Implementation

Lines 32 to 35 in 0525e9b

	(defn ^:private safe-counter! []
	(-> counter
	(swap! inc)
	(str)))

According to the CUID specification, it is described as follows regarding the Counter part:

The counter will roll over if the value gets too big.

It seems like this part has been omitted in the implementation.

Yes. You are right. I'll look at it when I can.

In the meanwhile a pull-request can make things much faster ;)
