[FEATURE]: Add possibility to rename "some" keys when other still will not be filtered out.

[Travellerme]

Background Information

• Module Version: json-2-csv
• Node/Browser Version: 20.11.0

The issue I'm reporting is with:

• json2csv
• csv2json

I have...

• searched to see if an issue has already been reported.
• verified that my JSON/CSV data is valid (using something like http://jsonlint.com or https://csvlint.io/).
• tried upgrading to the latest version of json-2-csv (since the issue may already be fixed).

Expected Behavior

I need to rename some fields and leave the auto-detect mechanism in place. It would be nice to add a possibility to rename "some" keys when other still will not be filtered out.
Add a new flag that would include all fields that are not specified in keys option. (for instance includeAutoDetectedKeys)

Actual Behavior

Currently, there is an option to provide a title only for keys that should be in the final csv file. That means I need to specify all fields I want to see and other fields will be skipped.

{
"field": "string", // required
"title": "string", // optional
"wildcardMatch": false, // optional - default: false
}

When specifying keys as an Object, the field property specifies the key path, while title specifies a more human readable field heading.

Data Sample

JSON:
ANY JSON file

Code Example

// Please include a simple example to replicate the issue
let converter = require('json-2-csv');
json2csv(list, {
    escapeHeaderNestedDots: false,
    unwindArrays: false,
    keys: [{
      field: 'data.businessDescription',
      title: 'Business Description'
    }],
    includeAutoDetectedKeys: true,
    emptyFieldValue: '',
    checkSchemaDifferences: false,
    expandNestedObjects: true,
    expandArrayObjects: true
  })
