Add Activity View API

[benox3]

This will be the api that drives the activities views. The idea here is to make a scalable and straightforward way to build activities with friends making video chat a first class citizen.

ActivityState: { // Available Globally
  peers: Peer[]; // All active peers
  activePeerIds: string[]; // All active peer ids
  selectedPeerId: string; // The currently selected peer id
  timer: null | number; // null if not set
}

Events:
onPeerAdded(peer)
onPeerRemoved(peer)
onPeerSelected(prevSelectedPeer, nextSelectedPeer)
onTimerStarted(activityState)
onTimerFinished(activityState)
onActivityStart(activityState)
onNext(activityState)

Actions:
getActivePeersLength();
getRandomNumber(min, max);
selectPeer(peer.id)
selectNextPeer()
selectPreviousPeer()
selectRandomPeer()
movePeerToPosition(peerId, position)
setPeerText(peerId, text);
setCenterText(text);
setTimer(time);
setActivePeers(peerIds)
forEachActivePeer();
requestText();


// Guess Who Game
{
  onActivityStart(() => {
    forEachActivePeer((peer) => {
      requestText(() => setPeerText(peer.id));
    })
    selectRandomPeer();
  }),
  onPeerSelected((prev, next) => {
    movePeerToPosition('center');
    setCenterText(next.peerText);
  }),
  onNext(() => {
    selectNextPeer();
  })
}
