AnnualDate class

Represents an annual date (month and day) in the ISO calendar but without a specific year, typically for recurrent events such as birthdays, anniversaries, and deadlines.

In the future, this class may be expanded to support other calendar systems, but this does not generalize terribly cleanly, particularly to the Hebrew calendar system with its leap month.
