Send events via a channel from anywhere (eg. web-dom, c-ffi) to Bevy Observers.

Inspired by [bevy_crossbeam_event](https://github.com/johanhelsing/bevy_crossbeam_event) but delivering the events via Bevy Observers instead of `EventReader`.

# example

```rust

#[derive(Event)]

struct MyEvent(i32);

fn main() {

    use bevy_channel_trigger::ChannelTriggerApp;

    let mut app = App::new();

    app.add_plugins(MinimalPlugins);

    // create channel

    let sender = app.add_channel_trigger::();

    // use sender from anywhere:

    thread::spawn(move || {

        let mut counter = 1;

        loop {

            // send events back to bevy

            sender.send(MyEvent(counter));

            thread::sleep(Duration::from_secs(1));

            counter += 1;

        }

    });

    // register an observer to receive the events sent via `sender`

    app.observe(on_event);

    app.run();

}

// regular bevy observer to handle these events coming into the bevy world

fn on_event(trigger: Trigger) {

    let event = trigger.event();

    println!("trigger with: {}", event.0);

}

```
