Support component wrapper

[CraigCav]

It's often necessary to wrap components to include things like global context providers, data stores, etc. It's also not uncommon for components to be reliant on "global" resource (such as fonts) to have been already loaded prior to taking a snapshot.

We should consider how we might extend the Sosia API to enable users to pass a React Component as a wrapper option to have it rendered around the inner element.

Other testing tools, such as React Testing Library use a similar approach.
