Use x-nullable extensions when reading/writing OASv2

[Jean-Baptiste Muscat (ouvreboite)]

While OASv2 does not have built-in support for nullable, the x-nullable extension is often used.
Could it be supported for OASv2 serialization or deserialization? Maybe as an optional setting in the writer and reader?
