Lock-free static variables.

## Examples

### Static variable

```rust
use lock_free_static::lock_free_static;

lock_free_static!{
    static VAR: i32 = 123;
}

fn main() {
    assert!(VAR.init());
    assert_eq!(*VAR.get().unwrap(), 123);
}
```

### Mutable static variable

```rust
use lock_free_static::lock_free_static;

lock_free_static!{
    static mut VAR: i32 = 123;
}

fn main() {
    assert!(VAR.init());

    let mut guard = VAR.lock().unwrap();
    assert_eq!(*guard, 123);
    *guard = 321;
    drop(guard);

    assert_eq!(*VAR.lock().unwrap(), 321);
}
```
