Function each

each<V>(consumer: (item: NoInfer<V>) => unknown): Sink<V, number>
Creates a sink handing every item to a consumer.

Items are handed over in source order. This is the sink of choice for pipes run for their side effects rather than for a collected result.
Warning
- Exhaustive: every item is handed over before the sink resolves, so an infinite feed never completes.
- Streaming: items are handed over one at a time, none retained.
- Stateful: the resolved count covers the items drawn, so a sink closing a nested or truncated feed counts those alone.
Type Parameters
- V
  The type of items in the feed
Parameters
- consumer: (item: NoInfer<V>) => unknown
  The function processing each item; a returned promise is awaited before the next item is pulled, so items are processed one at a time
Returns Sink<V, number>
A sink resolving to the number of items handed to consumer
Example
```
await pipe(
  (items([1, 2, 3]))
  (each(n => console.log(n)))
);  // logs 1, 2, 3; 3
```
