[DiljohnSingh]

Pull request type

New feature (non-breaking change which adds functionality)

---

Description

• Currently slidesPerView is hardcoded to be 1 and not a configurable prop.
• Some of the siemens projects using Mendix had to create custom widgets to display more than one slide into view.
• Adding two new slide configs/props. (slidesPerView & slidesPerGroup).
• Default value is still set to 1 to follow default behavior.
• Added useMemo for carouselItems.

What should be covered while testing?

• You should see two new configs(slidesPerView & slidesPerGroup).
• Play around with configs to see the changes into slides.
