Error: Domain not found for it.com domains

[lum8rjack]

I was using the DomainsDNS.GetHosts(domain) function to get the domain records for each of my domains, but would get a "Domain name not found (2019166)" error for each of my "it.com" domains.

I think I was able to trace it back to the ParseDomain function which uses publicsuffix.Parse(domain). From the publicsuffix-go library, the rules don't have the it.com domain in the tag that go-namecheap-sdk is currently using (v0.15.0).

I wanted to check if #45 pull request was close to being merged since it also updated the publicsuffix-go library, or if you would prefer I create a new pull request to update the library.
