Fixes #1541 and is an alternative, simpler implementation of #1650
this adds an
embedNullableUDA which specially treats std.typecons.Nullable without values as not defined. This makes it ignored during serialization.
This transparently makes the type hidden for a serializer if it's not given and thus allows special states like:
undefined== Nullable!T.init (not in output at all)
null== Nullable!T(null) (in output like usual for T == null)
value== Nullable!T(value) (in output like usual)
@optionalto keep backwards compatibility and avoid ambiguous definitions of "what's the ignored value" for an optional value.
