updateSubAdapterVisibleRange

open fun updateSubAdapterVisibleRange(firstVisiblePosition: Int, lastVisiblePosition: Int)

Updates the visible range when in sub adapter mode. Do not call this otherwise. This method exists because in sub adapter mode, the RecyclerBinder is never mounted to a RecyclerView and needs outside signals from the multiplexing adapter to determine which of its indices are visible.
