calc_rad_loss(): changed delimiter when calling dropwhile() (forgot to do that in a previous commit) and changed replaced usage of csv.DictReader with csv.reader as chianti_rad_loss.csv currectly has no column headings unlike temperature and emission measure data files and so csv.DictReader cannot be used.
