[FEATURE] Compile system code

[DriesSmit]

Feature

Create a feature which allows a system to save its complete code to file.

Proposal

This component would provide a system with a .compile() functionality. When one calls .compile() it generates files with runnable code in it. This code reproduces the system with its current components. However, the goal is that these files would be much easier to understand as they do not contain callbacks. Just the code contained in the callbacks. Therefore we still have the composability of Mava, but we also add some interpretability.
