Guarantee an increasing sequence in the onVmsSubscriptionChange message
First, instead of passing a sequence number and a list of layers, wrap
them in a parcelable object.
Then, generate the sequence number when updating the set of
subscriptions. In this way, we guarantee that different snapshots of
the subscription data have different sequence numbers.
