buildTimelineItem (seen) does not work properly

Hello Ramon, fantastic little library you've made here. Thanks :)
I think 've encountered a bug.

As documented in stories structure,
there is a key (seen: false, // set true if user has opened)

When in array of stories I put seen: true for one out of 5 stories (say for id="ramon").
I expect its ring to discolor & the story to go last.

Outcome observed: Story does go to last but the ring is not discolored as class "seen" is not added.

I patched together a fix in my code, sharing here.

In \src\zuck.js make changes to reflect accordingly in \dist\zuck.js (webpack)

Underneath
/* api */ zuck.data = option('stories') || {};
I created an array containing id of stories that have set key seen: true
const seenStoryIdsArr = zuck.data.filter(function(obj){ return obj.seen == true }).map(function(story){ return story.id; });

This I then pass the array variable as a second argument to function getLocalData wherever it is called, such as
zuck.internalData.seenItems = getLocalData('seenItems', seenStoryIdsArr) || {};

This function I then define as
const getLocalData = function (key, seenStoryIdsArr) { if (option('localStorage')) { const keyName = zuck-${id}-${key}`;

    return window.localStorage[keyName]
      ? JSON.parse(window.localStorage[keyName])
      : false;
  } else {
    // return false;
    const seenStoryIdsObj = {};
    for(var i=0;i<seenStoryIdsArr.length;i++){
      var keyName = seenStoryIdsArr[i];
      seenStoryIdsObj[keyName] = true;
    }
    return seenStoryIdsObj;
  }
};`

P.S. The code works just fine if key localStorage: true
