Updating TLDs

To update non-extended TLDs, IANA publishes, you can retrieve them from data.iana.org.

After retrieving the updated list, enter them into the file tlds-alpha-by-domain.txt. In order to update the TLDs map in tlds.go, you can run the gen.sh script which will generate the contents of a string -> bool map. After that, you'll want to replace the contents of the existing TLDs map, with the one that was generated and stored in formatted_tlds.txt
