This function caches the currently ingested index frame (and may be eventually renamed). It can use the stored index as a backup for map functions like groupIdForStreamId and can be used for:

• Maintaining consistent information during a subscribe even if an index is received concurrently
• Maintaining information about previous senders simulcast streams to enable stream switching, e.g. if a sender is transmitting low/hi and switches to just low, receivers need the previous index to be able to know what group ID the high stream corresponds to.
