docs: Create the singles buffer
  
          This creates the singles buffer for each ifo. The dtype is determined
          by a representative sample of the single triggers in the results.
  
          Parameters
          ----------
          restuls: dict of dict
              Dict indexed by ifo and then trigger column.
