feat: support for full result object in node streams

README.md

@@ -55,7 +55,7 @@ Papa Parse for Node
 
 Papa Parse can parse a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) instead of a [File](https://www.w3.org/TR/FileAPI/) when used in Node.js environments (in addition to plain strings). In this mode, `encoding` must, if specified, be a Node-supported character encoding. The `Papa.LocalChunkSize`, `Papa.RemoteChunkSize` , `download`, `withCredentials` and `worker` config options are unavailable.
 
-Papa Parse can also parse in a node streaming style which makes `.pipe` available.  Simply pipe the [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) to the stream returned from `Papa.parse(Papa.NODE_STREAM_INPUT, options)`.  The `Papa.LocalChunkSize`, `Papa.RemoteChunkSize` , `download`, `withCredentials`, `worker`, `step`, and `complete` config options are unavailable.  To register a callback with the stream to process data, use the `data` event like so: `stream.on('data', callback)` and to signal the end of stream, use the 'end' event like so: `stream.on('end', callback)`.

When using this style, the callback will receive only the row data by default. Set the config option `streamIncludeMetaAndErrors` to `true` to instead instead recieve the [standard Parse Result object](https://www.papaparse.com/docs#results). This result object will be atomic to the individual row passed to the callback (`errors` are not cumulative, and `data` is a single row instead of an array of rows).
