[FEATURE]: Use externally provided class

[Azbesciak]

I would like to use a class implementation provided in the schema, not providing a mirror of it, but just reusing the one already in the dependencies.

One example is geojson schema, where I have my geometries classes already in dependencies and I want to avoid duplicating them, and then mapping to my classes. Or maybe it is already possible?

Context (Input, Language)

Input Format:
json schema

Output Language:
java, but would benefit for all

Description

• avoid unnecessary mapping
• reusability of classes

Current Behaviour / Output

Maybe it is possible but right now I need to map one by one created classes to my desired ones

Proposed Behaviour / Output

There would be some "magic" property in schema which indicates the class. Or maybe in the renderer properties, to address $ref, somehow.
