Switch to using retour for better cross-platform support

[ccptr]

I'm planning on adding Linux support if you're open to it. I tested it on Windows and the behavior hasn't changed. Using retour also has the advantage of being written in Rust, so it's one less system dependency :)

This can also be wrapped in ManuallyDrop instead of storing it in the struct below

Any input on this? I'm actually planning to turn this into a CS2 base as a library. I'm hoping to make something where you can pretty much just cargo init && cargo add cs2lib, and then do something along the lines of:

use cs2lib::{Hooks, make_entry_point};

unsafe extern "system" fn create_move(a1: *mut f32, a2: u64, a3: i8, a4: u64, a5: u64, a6: u64) -> u64 {
    println!("create move called");
    originals::create_move(a1, a2, a3, a4, a5, a6)
}

fn startup() {
    let hooks = Hooks {
        create_move: Some(create_move),
        // add the rest of the functions you want to hook here
        ..Default::default()
    };

    let originals = cs2lib::initialize(&hooks);
}

make_entry_point!(startup);

The cheat developer would get type checking for hook functions, signatures for hooks, and would make it easier to contribute due to the library not being coupled with the cheat, making it easier for everyone when CS2 updates break things.

I completely understand if you're not interested in doing this, but if you're willing to just add Linux support please let me know, as I have a PR in the works that I'll just squash if you're not interested.

+1 for Retour also a +1 If you would add a Offset Manager.
Maybe also some Interfaces. The pointer on the create_move (a1) seems to be a bit buggy when used with the default CInput interface.
But in all would love to see this being more developed.
