Pull requests consist of the following changes:

• constant's type changed from u32 to i32 to stay consistant with winapi constant's type
• listen method modified to interupt infinite loop when WM_QUIT message received
• added post_quit_message helper function that simply calls PostQuitMessage that sends WM_QUIT
• added a bit of docs for listen and post_quit_message

From PostQuitMessage docs:

Indicates to the system that a thread has made a request to terminate (quit).

I have verified that posting WM_QUIT by calling PostQuitMessage message from different process have no effect on the listen loop.

There are a couple places in the code where you do something along the lines of

let mut event: SomeType = mem::MaybeUninit::uninit().assume_init();

This is immediately undefined behavior, regardless of the type. The 2 scenarios I have seen this in the codebase are in the context of a C-style return parameter, so the fix is rather simple.

let mut event: MaybeUninit<SomeType> = mem::MaybeUninit::uninit();
// Maybe attempt to handle a potential int-code error this function may return?
get_event(event.as_mut_ptr());
let event: SomeType = event.assume_init();

Is this library still maintained? There's some forks with macOS support (https://github.com/gamebooster/soundboard/blob/master/extern/hotkey-rs/src/macos.rs) but I didn't test it yet. Would you accept a PR with that?
