docs: Returns the interval format with the given Id (see CLDR documentation for valid Ids)
  or the fallback format if no interval format with that Id is known.
  
  The empty Id ("") might be used to retrieve the interval format fallback.
  
  @param {string} sId Id of the interval format, e.g. "d-d"
  @param {sap.ui.core.CalendarType} [sCalendarType] the type of calendar. If it's not set, it falls back to the calendar type either set in configuration or calculated from locale.
  @returns {string} interval format string with placeholders {0} and {1}
