Adds converter and deserializer which bridges conversions between `kotlin.time.Duration` and `java.time.Duration`.

Notes:
* later Kotlin version adds dedicated method `kotlin.time.Duration.toJavaDuration()` which can be used instead ISO parsing (in converter)
* ...and adds dedicated extension method `java.time.Duration.toKotlinDuration()` which can be used instead ISO parsing (in deserializer)

In order to properly deserialize data class with duration following hacks are needed:
* class need to have explicit static factory annotated with ``@JsonCreator`, primary ctor won't cut it
* in data class definition value-class getter has to be annotated with Duration converter

Kotlin Duration is value class and as Jackson has limited support of such cases it falls under few limits:
* data classes with Duration needs to have explicit creator method
* Duration fields has to be annotated with explicit `@JsonDeserializer` annotation

See `DurationTests` for details.
