Fetch keys from other namespace

[prakashchokalingam]

Currently, we have a global config of namespace & delimiter. Once configured the local storage hooks can read keys of a given namespace only.

Yet there might be use cases especially in micro frontends where we might need to fetch keys from a different namespace. Hence proposing the solution of overriding the default config by providing the config as args to the hook.

const [user] = useLocalStorage('user', { namespace: 'global', delimiter: '#' })
