Function tap

tap<T, E>(
ra: ResultAsyncType<T, E>,
fn: (value: T) => void | Promise<void>,
): ResultAsyncType<T, E>
Run a side effect on the success value without altering the result. The side effect is awaited if it returns a Promise. The original ok or err flows through unchanged.

Dual API — works data-first or curried for use in pipe.
Type Parameters
- T
- E
Parameters
- ra: ResultAsyncType<T, E>
- fn: (value: T) => void | Promise<void>
Returns ResultAsyncType<T, E>
Example
```
pipe(
    fetchOrder(id),
    ResultAsync.tap(order => logger.info("loaded", order.id)),
  )
```
