val iter:
        cancellationToken: CancellationToken -> handler: ('T -> Task) -> source: IAsyncEnumerable<'T> -> Task<unit>
```

Awaits one handler at a time for each item until the stream ends.

The helper disposes its enumerator but leaves the control client open.

## Parameters

- `cancellationToken` (`CancellationToken`)
- `handler` (`('T -> Task)`)
- `source` (`IAsyncEnumerable<'T>`)
