Feature new corusel template

[YaroslavKozhemiaka]

Now you can add rich media message / carousel content message in another way
Example

$carousel = Carousel::create(6,3)->addElement(
            CarouselElement::create('<font color="#FFFFFF">Text1</font>',6,1),
            CarouselElement::create('<font color="#FFFFFF">Text2</font>',6,1),
            CarouselElement::create('<font color="#FFFFFF">Text3</font>',6,1)
        );

$this->say("Default text",$carousel->toArray());
