excelStrings option works incorrectly with quoted values

[mikhalev-im]

Version of json2csv: 5.0.5
Node version: 12.19.1

Code:

const { Parser } = require('json2csv');

const parser = new Parser({
  header: false,
  delimiter: ';',
  excelStrings: true,
});

const data = {
  field1: 'string',
  field2: '"quoted"'
};

parser.parse(data);  // result: "=""string""";"=""""quote"""""

If you write the result to a file and open it in excel, there would be an error in a quoted value:

The tooltip is saying that the formula has an error.
