When streaming writes with nodejs, `csv-stringify` will return twice amount of quotations if the line contains nested json objects

Describe the bug

When using the latest csv-stringify@6.0.5 or the @5.x versions, when I use write streams to create csv files out of objects, it will add twice amout of quotations as expected. e.g. "{""id"": ""random-hex"", ""count"": 1, ""user"":""userID""}"

To Reproduce
The code to reproduce:

const fileStream = fs.createWriteStream(writeFile, { flags: 'wx' });
const jsonArray = [
  {
    id: { nested: 'random-hex' }, // nested object
    count: 1,
    user: 'userID',
  },
  {
    id: { nested: 'random-hex' },
    count: 1,
    user: ['userID'], // array
  },
];
stringify(jsonArray, {
  header: true,
  // cast: {
  //   object: function(val) {
  //     return JSON.stringify(val);  // tried using stringify but did not work out
  //   },
  // },
}, function(err, output) {
  if (err) {
    console.error(err);
  }
  fileStream.write(output);
}).on('finish', () => console.log(`Done writing to:  ${writeFile.yellow}`));

will give out:

id,count,user
"{""nested"":""random-hex""}",1,userID
"{""nested"":""random-hex""}",1,"[""userID""]"

Was wondering how to parse those special fields (I assume is something with cast) so that it is in the format of JSON. Expected to be:

id,count,user
{"nested":"random-hex"},1,userID
{"nested":"random-hex"},1,["userID"]

Thanks in advance!

Start by running the reproduction with csv-stringify, Node.js write streams, and the nested object and array values shown in the issue. Trace how those values are serialized and quoted, then verify the output against the expected CSV examples while preserving correct handling of ordinary fields.
