Split react adapter helper components into another package

[mihkeleidast]

What problem would this feature solve?

Currently, when a library uses the PathProvider helper component and depends on it, it also makes it mandatory to install the main @frctl/fractal package in an application that uses the library. This is because @frctl/react requires it as a peerDependency. This is unnecessary, since using only the helper component as a transitive dependency should not mandate using or installing the main Fractal module in an application.

What the feature should look like?

• Split the components directory in the React adapter into another package, @frctl/react-components.
• Keep the exports in the React package to provide backwards compatibility.
