Updated to RUST 2024 & rustc 1.88.0-nightly

Hey Gian!

... I prefer it without external crates too ...

I managed to implement your Mutex everywhere and even added it to the files where you had warnings:

//Warning! Mutable static here
//TODO: Implement a mutex to get safe access to this

It wasn't as difficult as it seemed at first. The key to the solution is in the raw pointers. So to access the static mut XYZ like there:

FAT.acquire().list_entries();
FAT.free();

Now you must write like this:

((&raw mut FAT)).acquire().list_entries();
((&raw mut FAT)).free();

Accordingly, I had to adjust and move some unsafe {} ...

The code now compiles and runs without errors or warnings on the latest nightly build 1.88 rust 2024
