Adapter for Jackson 3.0

Is your feature request related to a problem? Please describe. Jackson 3 has been released a few days ago. It introduces a namespace change and api changes.

Describe the solution you'd like Jackson 2.x is probably here to stay for a long time. So the idea would be to have a new adapter for jackson 3.x while still keeping the 2.x one.

Describe alternatives you've considered Jackson 2 and Jackson 3 can probably live together in the same classpath but having a jackson 3 adapter for this project would be nice.

Additional context The next release of the widely used spring framework will also favor Jackson 3.x while still keeping the possibility to work with Jackson 2.x. The release after will likely drop support for Jackson 2.x.

Are there any plans ? Would a pull request addressing this be useful ? (no promises...)
