[Feature] : Add a default value for data

As initialValue only works for server-side rendering, it could be nice to have another prop (ex: defaultDataValue) so that we can controll the initial value of data.

const { data } = useAsync({ promiseFn });
const { todos = [], userPreferences = null } = data || {};
