Make tldextract work more efficiently

[Kairixir]

Done using tldextract. Might be useful to rewrite, it takes a long time. They check every TLD using the Public Suffix List (PSL). I believe they manage the whole list inefficiently. Might be useful to rewrite it into using Trie, or Tree over first letters + Dict over the leftover
