Parent data in custom converter

[andreas-aeschlimann]

As of now, the JsonCustomConvert interface has the methods serialize(data: T): any and deserialize(data: any): T.

In some cases, the (de-)serialization might be dependent on the parent's object values. We could add an optional parameter parentData?: any in both methods that contains the parent data (object) if it exists, undefined otherwise.

This is exactly the feature I currently need and that's why I came across this issue.

Would be great if a context could be passed.
Then this could be extended in the future with other useful data.

A reference to the jsonConvert instance would be also nice. In some use cases I needed access to it in order to manually (de)serialize something.
