class_docstr: HolidayCalendar implementation.
  
  Requires the calendar to be bounded. Constructs tables of precomputed values
  of interest for each day in the calendar, which enables better performance
  compared to a more flexible UnboundedHolidayCalendar.
  
  Each instance should be used in the context of only one graph. E.g. one can't
  create a BoundedHolidayCalendar in one tf.function and reuse it in another.
