GLB Optimizations and Improved Toolbar

I got the regenerate+re-render times down to about 800ms. The biggest part was actually just letting the browser’s JIT compile the hot parts so that subsequent regens would run way faster. It only takes 1 eval to get there, although that one eval is about 15 seconds. After that its super fast.
Another thing I did was switch to the GLB file format for transfering mesh data between build123d and three.js. GLB is very compact and encodes+decodes super fast. This took the encode + parse time from 3 seconds to about 100ms. I’d really like to be able to cache the “JIT”ed WASM between page loads and apparently the browser should do this already but it’s clearly not.

I also worked on the toolbar and used Bits UI to get a really nice search function with the features. I want to have a nice reusable interface for defining features with an automatic UI builder which would also make an equivalent to OnShape’s FeatureScripts super easy to implement (literally just a build123d generator with some UI bindings).
