JsonTypeConverter<D, S> mixin Null safety

A mixin for TypeConverters that should also apply to drift's builtin JSON serialization of data classes.

By default, a TypeConverter only applies to the serialization from Dart to SQL (and vice-versa). When a BuildGeneralColumn.map column (or a MAPPED BY constraint in .drift files) refers to a type converter that inherits from JsonTypeConverter, it will also be used to conversion from and to json.
