 * a small extension to the Zumba\Util\JsonSerializer to allow deserializing mongodb legacy driver objects
 *
 * NOTE: this is only needed as we widely use the "mongodb legacy" driver (pecl/mongo) instead of the newer one
 * (pecl/mongodb) - if we once switch to the new driver, we should be able to ditch this.
