Describe the bug

There is no way to quote empty strings without also quoting null and undefined values. I expect that empty string will be quoted and null / undefined values will not be quoted when options quoted_match: /^&/ and quoted_empty: false are provided. quoted_empty: true will quote empty strings, but it will also quote null and undefined values.

Node version: 16.13.2
csv-stringify version: 6.1.2

To Reproduce

import { stringify } from "csv-stringify";

stringify([
  ["a", null, undefined, "", "b"],
], {
  quoted_empty: false,
  quoted_match: /^$/,
}, (_, csv) => {
  console.log(csv);
});

Output: a,,,,b
Expected output: a,,,"",b
