JsonTypeConverter2<D, S, J> mixin
A mixin for TypeConverters that should also apply to drift's builtin JSON serialization of data classes.
Unlike the old JsonTypeConverter mixin, this more general mixin allows
using a different type when serializing to JSON (J) than the type used in
SQL (S).
For the cases where the JSON serialization and the mapping to SQL use the
same types, it may be more convenient to mix-in JsonTypeConverter instead.
