a function to call on each chunk of the stream. Async or not.
Optionaloptions: Stream.ArrayOptionsa promise evaluating to the first chunk for which fn evaluated with a truthy value,
or undefined if no element was found.
This method is similar to Array.prototype.find and calls fn on each chunk in the stream
to find a chunk with a truthy value for fn. Once an fn call's awaited return value is truthy,
the stream is destroyed and the promise is fulfilled with value for which fn returned a truthy value.
If all of the fn calls on the chunks return a falsy value, the promise is fulfilled with undefined.
