Adding the ability to long click touch events for each image.

Hi @sayyam! Is it possible to accept the pull request and release a new version? Or is this library not maintained anymore?

A workaround:

imagesCarousel.setImageListener { position, imageView ->
    imageView.setOnLongClickListener {
        onLongClick(position)
        return@setOnLongClickListener true
    }

    imageView.setOnClickListener {
        onClick(position)
    }
}
