Use a bundler

[JovannMC]

At some point, SlimeTora should use a bundler (e.g. webpack or rollup) to bundle the code which will help with performance - I've tried getting this working before and it hasn't worked (really shows how good I am at programming 😅).

This does have the unintended side effect of being much harder to get testing builds up for people if it requires an update to haritorax-interpreter though, as I literally extract the app.asar and replace it with an unpublished version.
