1.float转double报错
报错类型：
Max allowed object depth reached while trying to export from type System.Collections.Generic.List
序列化时候会遇到float和double互转问题；
注意这里double转float会导致精度丢失；
解决办法：
JsonMapper.cs中添加几行代码；
2.Dictionary中key为int时报错
报错类型：
InvalidCastException: Specified cast is not valid
原方法中Dictionary的key只支持（string）强转，int强转为string失败，会报错；
解决办法：
JsonMapper.cs中WriteValue方法修改
3.Dictionary中key为enum时报错
LitJson的字典不支持Key为枚举；
序列化不会出错，反序列化会报错，无法读取枚举类型；
解决办法：
修改JsonMapper.cs中ReadValue方法：
原本reader.Value被强转为string，无法识别出枚举；
下面将reader.Value转为Object；
4.Unity中LitJson类型扩展
添加向量Vector2、Vector3、Vector4；
添加四元素Quaternion、Color、Color32；
添加Bounds、Rect、RectOffset；
项目中加入UnityTypeBridge.cs类和JsonExtension.cs类；
