support "type": ["object", "null"]

I need to set "type": ["object", "null"] in my json schema, but haven't found a way to do this. Is there a way?

For now I use Reflect and then set .Type = "[object, null]" and then when the schema is done I do a replace all.. it works, but is a little hacky

No file or test is named. Start by tracing how the Go generator represents and emits the JSON Schema type from reflected fields, then compare that path with the reported Reflect workaround. Done means a schema can express "type": ["object", "null"] without a post-generation replacement, with coverage for the generated output.
