  Emits a sequence of `usize` values on every interval tick.

## Example

Run the example with:

```sh
cargo run -p rx_core --example observable_timer_example
```

```rs
let mut mock_executor = MockExecutor::new_with_logging();
let scheduler = mock_executor.get_scheduler_handle();

let mut timer = TimerObservable::new(Duration::from_secs(1), scheduler);
let _subscription = timer.subscribe(PrintObserver::new("timer_observable"));

mock_executor.tick(Duration::from_millis(600));
mock_executor.tick(Duration::from_millis(400));
```

Output:

```txt
Ticking... (600ms)
Ticking... (400ms)
timer_observable - next: ()
timer_observable - completed
timer_observable - unsubscribed
```
