v3.2.701 版本自定义类型转换

class Product

public Guid id { get; set; }
[Column(MapType = typeof(string), StringLength = -1)]

}
public override JsonClass Deserialize(object value)
{
return JsonConvert.DeserializeObject<JsonClass>((string)value);
}
}
```
使用 MapType 枚举 -> string/int 等等如下：
```csharp
class EnumTestMap {
public Guid id { get; set; }
