Add `JsonLd::addValues()`

[klimov-paul]

Working with JSON Linked Data usually means specification of the batch options.
For example:

{
   "@type": "Organization",
   "'address" : {
        "@type": "PostalAddress",
        "addressLocality" : "USA, CA",
        "postalCode": "12345",
        "streetAddress": "2nd ave, 17",
    },
    "email": "organization@example.com"
}

Creation of such JSON at the present state requires multiple invocations of JsonLd::addValue().
It is better to create a shortcut for adding batch of values at once - JsonLd::addValues()
