Description

Error: TLD <domain with one of the aforementioned TLDs> not found
    at whoisTld (whoiser.js:118:9)
    at async whoisDomain (whoiser.js:137:15)

Side Note: Phenomenal work on this utility. I reviewed a few similar options on npm, and your dedication to quality made whoiser the clear winner.

this is not kinda fixed by #86

To query WHOIS for a domain, the library needs to know the WHOIS server for that TLD. It finds it in this order:

1. cached/hard-coded whois server https://github.com/LayeredStudio/whoiser/blob/master/src/whoiser.js#L9
2. query whois.iana.org for TLD info
3. when no tld.whois is found, query alternate TLD sources Third Level Domains, Additional TLDs, & Bug Fixes #80

The error was returned because tld.whois was empty. Now the library doesn't throw an error, but it returns the TLD info without whois. Example for .vn:

For cases like these, the TLD whois server needs to be found and added in the whoiser.js -> cacheTldWhoisServer variable
