IPv6 addresses not working as expected

[cchretien]

Hello,

Thanks for creating this library. I'm not an IPv6 expert but I started playing around with IPv6 addresses and the execution just hangs. Are we limited to only a shorthand IPv6 address of 3 groups?

node --version
v14.18.2

Example

const { getIPRange } = require('get-ip-range');

const range = getIPRange('2620:11b:d06c:11c5:ffff::1', '2620:11b:d06c:11c5:ffff::14');
const range = getIPRange('2620:11b:d06c:11c5:ffff::1/123');

I tried using this PR branch and seems to address my issue. #32

Anyway we can get his merged and published? Or is the project considered deprecated?
