This updated the regex used to validate that a string is a valid IPv6 CIDR. The complex regex here was NOT developed by me, from scratch, but taken from the widely used "cidr-regex" npm package.
Given its widespread use, and that it successfully categorized all tests I threw at it (Which consisted of the list of reserved IPv6 ranges on this wikipedia page: https://en.wikipedia.org/wiki/Reserved_IP_addresses), I believe it is correct.
