title: Make redux-persist to notify me when data are restored
body: <p>I have large amount of data that I'm storing in local storage using react persist. What I need is to know when persist data were restored in my reducer (when app is loading). I need to validate  data version and I need to generate lookup object (which redux-storage us unable to store,  probably because  because it has around 65405 records/fields).</p>
  <p>Anyway I would like to know when react-persist is loading my data so I can work with them. How do I achieve this?</p>
