Exception during Serializer generation

[FrankHossfeld]

Using a POJO as key of a Map will crash the generation.

The attach small project produces the exception. just ran mvn clean package

So this is actually an issue domino-jackson rather than in domino-rest and in domino-jackson there is a fixed set of mappers types for map keys.

https://github.com/DominoKit/domino-jackson/blob/3f925e9a28d146b93e520f44de21f47ded9ec51e/domino-jackson-processor/src/main/java/org/dominokit/jackson/processor/TypeRegistry.java#L515

But maybe this can be implemented to allow custom (de)serializers.

Well, of course, that would be cool. On the other hand, I think this is quite a unusual case ...
