Ideas how to reduce the library size

[timocov]

The main concerns:

• Our pipeline knows how to minify our code much much better (by using https://github.com/timocov/ts-transformer-properties-rename + terser properties mangling) thus it cannot be done on the consumer side (in the apps) or we have to declare how to minify our app?
• Probably we can start to load some code asynchronously, but which one and how to load it (I mean, so every consumer will understand that)?
• Code splitting/Tree shaking (it seems that we need to write the code in different manner for this? how?)
