Optimize template render

Created by: kachurun

I wanted to start using twing instead of twigJS and the first thing that worries me is rendering performance, so I did a little test of a simple template render and found that the twing rendering time was slowed down 50-150 times relative to twigJS. Maybe I'm doing something wrong? Demo is here: https://codepen.io/kachurun/pen/yLyJaxB
