Add support for Java-tuples datatypes (as part of jackson-datatypes-collections?)

[cowtowncoder]

(note: FasterXML/jackson-databind#2020 is the background)

Tuple types from https://www.javatuples.org/ do not work out of the box, both due to immutability which requires builder-based construction (or use of "mutant factory" methods), and since getters do not (necessarily) exist for serialization -- and even if they did, would result in sub-optimal presentation.

But adding custom serializers, deserializers for 10 or so types seems quite simple.
