Support to undefined values

[arshadkazmi42]

if a key is missing from the request data, add handler to support that or give proper messaging.
Example:

const ChromeCookie = require('chrome-cookie');
const CCookie = new ChromeCookie();



const DATA = [
      {
        'creation_utc': 'now',
        'encrypted_value': 'enc2',
        'expires_utc': 'never',
        'has_expires': 'yes',
        'host_key': 'youtube.com',
        'is_httponly': 'yes',
        'is_persistent': 'no',
        'is_secure': 'yes',
        'last_access_utc': 'now',
        'name': 'youtube',
        'path': '/root',
        'priority': 'no',
        'value': 'kazmi',
        'samesite': -1,
        'encrypted_value': {}
      }
    ];

CCookie.setCookie(DATA);

above code breaks if we remove encrypted_value
