updateSubAdapterWorkingRange

open fun updateSubAdapterWorkingRange(firstVisibleIndex: Int, lastVisibleIndex: Int, firstFullyVisibleIndex: Int, lastFullyVisibleIndex: Int)

Updates the working 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.
