Chain Field added to Event Stream

We've recently added a top level chain field to most event payloads from the Stream API to make it easy to identify which chain the NFT or Collection affected by the event is on. The field has been added to following events:

ItemListedEvent
ItemSoldEvent
ItemTransferredEvent
ItemReceivedBidEvent
ItemReceivedOfferEvent
ItemCancelledEvent
CollectionOfferEvent
TraitOfferEvent

To use the new field, updated the Stream SDK to version 0.1.2 or higher. For more information on the Stream API, view the developer docs.
