Return the `DayOfWeek::Enum` value that is the specified (signed) `numDays` from the specified `dayOfWeek`. Note that `DayOfWeek::Enum` is closed under this operation (in the expected manner). For example, the following hold `true`: ` DayOfWeek::e_MON == DayOfWeekUtil::add(DayOfWeek::e_SUN, 1); DayOfWeek::e_SAT == DayOfWeekUtil::add(DayOfWeek::e_SUN, ‐1); DayOfWeek::e_SAT == DayOfWeekUtil::add(DayOfWeek::e_SUN, 6); DayOfWeek::e_MON == DayOfWeekUtil::add(DayOfWeek::e_SUN, ‐6); DayOfWeek::e_SUN == DayOfWeekUtil::add(DayOfWeek::e_SUN, 7); DayOfWeek::e_SUN == DayOfWeekUtil::add(DayOfWeek::e_SUN, ‐7); DayOfWeek::e_MON == DayOfWeekUtil::add(DayOfWeek::e_SUN, 8); DayOfWeek::e_SAT == DayOfWeekUtil::add(DayOfWeek::e_SUN, ‐8); `
