`GenericJackson3JsonRedisSerializer` has Jackson 2 core dependencies

[desckapg]

Hello!

GenericJackson3JsonRedisSerializer incorrectly uses Jackson 2 class (om.fasterxml.jackson.core.TreeNode) instead of Jackson 3 equivalents (tools.jackson.core.TreeNode), creating a mixed-dependency serializer that contradicts a pure Jackson 3 implementation. According to the JSTEP-1 Jackson 3 will still use jackson-annotations 2.x., so ther're no problems with it

Good catch and thanks for the report. That's fixed now.
