parse stream will emit an error when newline is \r\n and the chunk data end with \r.

import { Readable } from 'node:stream';
import Papa from 'papaparse';

const stream = new Readable({
  objectMode: true,
  read() {},
});

Papa.parse(stream, {
  delimiter: ',',
  newline: '\r\n',
  skipEmptyLines: true,
  header: true,
  complete(results, file) {
    console.log(results.errors);
  },
});

stream.push('name,value\r\n');
stream.push('foo,"FOO"\r');
stream.push('\n');
stream.push(null);
