Reducing compiled module size

[benniekiss]

I've been working on shrinking the size of some lua modules, but I believe I've hit a wall where I can't get any module to compile to less than ~500kb after following the guidance in https://github.com/johnthagen/min-sized-rust

Interestingly, I noticed that non-module compilations end up around the tens of kilobytes, which is not what I would expect, but I am no expert.

Has anyone been successful in making smaller modules, and if so, how?
