Set the range of this calendar using the specified `firstDate` and `lastDate` as, respectively, the first date and the last date of the calendar. Any holiday that is outside the new range and its holiday codes are removed. See {Iterator Invalidation} for information regarding which iterators are affected by the use of this method. The behavior is undefined unless `firstDate <= lastDate`.
