Investigate existing carousel components

[muffinresearch]

Some of the new mocks feature carousels, it would be good to look at providing a single solution to this so that we can use one carousel for all these various implementations.

First step is to look at what existing solutions there are and what they do:

• TODO: Detail required features here.
• Is it responsive? Will it adapt to mobile?
• Is the implementation CSP compatible?
• Does it support slides partially shown?
• Is it easily customizable?

Few examples to evaluate.

• https://github.com/josephrace/react-carousel
• https://www.npmjs.com/package/react-responsive-carousel

Closing this - looks like react-slick is being used.
