Support reply-to header

PHP API Client should support replyTo parameter as API Freshmail has.

Here is one mistake, if replyTo email address is not set then code failed with message:

PHP Fatal error:  Uncaught Error: Call to a member function getEmail() on null in /Users/suchy/project/php-api-client-calthaeu/src/Messaging/Mail/MailBag.php:187

because we always want to retrieve property by method on object that was not initialize:

public function getReplyToEmail(): string
    {
        return $this->replyTo->getEmail();
    }

To fix code should look like this:

/**
     * @return string
     */
    public function getReplyToEmail(): ?string
    {
        if ($this->replyTo) {
            return $this->replyTo->getEmail();
        }

        return null;
    }

    /**
     * @return string
     */
    public function getReplyToName(): ?string
    {
        if ($this->replyTo) {
            return $this->replyTo->getName();
        }

        return null;
    }

and then it works perfectly
