Skeleton loader

[eriknson]

Let's introduce a flexible component to populate skeleton loaders arbitrarily in snaps custom UI. Devs can define width, height, and border-radius, which should cover most of our use-cases.

Suggested props;

• borderRadius
• width
• height

DS has merged their Skeleton Loader Component here:
