public class DurationIso8601Deserializer extends com.fasterxml.jackson.databind.JsonDeserializer<Duration>
Custom deserializer for Duration objects, allowing ISO 8601 duration strings to be parsed into Duration instances.

This deserializer supports durations in the format PnDTnHnMnS, where n represents days, hours, minutes, or seconds. It doesn't support months or years, as these aren't compatible with Duration.
