No bug - just a thanks

Hello @kmike , I'm working on the 3rd edition of our High Performance Python book, this is just to say a public Thank You for your continued support for the Marisa Trie. In my updated Less RAM chapter your Trie still has the fastest lookup time (and is faster than the newer `pygtrie` and `lexpy` DAWG). Feel free to close this, I just wanted to say Thank You. Ian.
