Allow nested Notification Contexts

[northkode]

Allow nested Notifications contexts by passing in a context unique ID into the
Notifications Component instead of importing a generic:
const context in the context.js file.

This will allow for different components to place notifications in different places of the app like top of a modal, or a root context for root global notifications etc

Now I'm busy developing a new version. There will be no context in it, therefore I have to close the issue. Sorry
