does not support mongoDB 6^ version, stuck because of this package

Hi,
This package is not supporting latest mongoDB version 6^, We are using this package for migration, now we are upgrading our application mongodb version to 6^, this package is creating problem , we are stuck because this package not supporting latest mongodb driver version 6^.

below code needs to be corrected

`db = config.db || new MongoClient(new Server(host, port));` in **index.js file**, because new Server() is not supported in latest mongodb driver.
