Since the reload logic no longer relies on any state, the relevant loop is simple enough that it feels clearest to include it in the main entry point file.
Instead, load the relevant module of the true file, and execute the modified code within that.
This also cleans up some of the previous now-unnecessary code around get_module_with_inserted_embed_line
* Experiment a lot with module loading
* Extract methods out of experimental mess
* Fix get module return type
* Only reload() modules during reload() command
* Remove unnecessary default parameter
* Add docstrings and logging statements
* Delete unwanted printout
* Improve logging messages
* Extract methods to a new class ModuleLoader
* Remove unused builtins import
* exec_module in any case at the end
* Clarify docstrings & move get_module method up in file
* Add more additionally excluded modules as array
* Distinguish between user-defined modules and external libraries like numpy
* Improved tracked_import docstring
* Remove _insert_embed suffix before logging
* Fix args.is_reload not defined error
* Refine logic to determine whether module is user-defined or not
* Fix list vs. set type annotations
* Improve docstrings & change order of early return
* Fix spelling mistake of "Reloading"
* Try out custom deep reload
* Make deep reload more robust
* Also reload modules imported as classes
* Move early return up to greatly improve performance
* Clean up comments
* Make methods of Module Loader "private"
* Add backticks around function in docstring
