Research direction

Investigate the current streaming API in PapaParse (e.g., Papa.parse with stream: true). The feature would require adding an async iterable version of the parse method. Look at existing async iterator patterns in Node.js and browser environments. Consider implementing a new option 'asyncIteration' that returns an async generator yielding rows. Since there are no comments, discuss the approach in the issue before implementation.
