refactor: Make the codebase more modular and easier to read

[kleidis]

Completed:

• A lazy importing module so communicating between modules on the codebase is easier
• Separated UI functions into ui_main for common functions and "__page" files for specific functions related to pages and the PyQT code itself"

In progress:

• Simplify and cleanup the refactored code

Still not started:

• Enhance the current functions to be more fool proof

Now Troppical fully works like it sued to before the refactoring
Although there is still more to do

I have had a look at the majority of the code. I am unsure on the ui code as I have very minimal experience with PyQt6.

The code being in modular chunks is a nice addition. I tested downloading MelonDS to a custom install location and it worked fine. Nothing in the code seems explicitly wrong. I've been a bit busy so I haven't been able to be as thorough as I would have liked.

One thing I noticed is that you were varied with how you started a few files in the ui section.

imports

class

imports
class

I think it is important to keep a consistent coding style.

Other than that everything seems okay and functions as expected.

I'll fix the inconsistencies at a later date. Thank you for going through this
