EventSource

Zero cost non buffered async event emitter

Example

```rust async fn main() { let source: Arc

// imaginary function for spawning future in another thread
spawn({
    let source = source.clone();
    async {
        let mut a = 35;
        emit!(source, &mut a);
    }
});

let mut output = 0;
// Closure can contain reference!
source.on(|value| {
    println!("Event emiited with value: {}!", value);
    output = *value;

    Some(())
}).await;

println!("Output: {}", output);

} `` This code outputsOutput: 35`
