getTags method needs to be able to pass count

[paulwrightabuk]

The default value for tags is 10, but there is no way to increase the value in the getTags method. For example, like this

public function getTags(string $email, string $listName = '', $count = 20)
{
$list = $this->lists->findByName($listName);

    return $this->mailChimp->get("lists/{$list->getId()}/members/{$this->getSubscriberHash($email)}/tags",
    ['count' => $count]);
}
