Clojurians Log v2

I'm implementing a major optimization of how schemas are created to tackle exponential memory growth. I have a prototype which I'd really appreciate some real-world testing for, especially if you use exotic registries. Primarily I'm interested if anything breaks. Secondarily, if it improves memory usage if you'd like to go the extra mile. Thanks! https://github.com/metosin/malli/pull/1284
