TransformEx扩展类

写了一个Transform的扩展类，可以单独设置Position的x或者直接设置Scale的整体缩放大小。
如果对静态类不了解的可以参考这里：https://www.jianshu.com/p/17ee1c7f23a5
先看一下调用方式：

using UnityEngine;

public class Test : MonoBehaviour
{
    Transform player;
    // Start is called before the first frame update
    void Start()
    {
        player = this.transform;
        player.SetLocalScale(5);
        player.Reset();
    }
}

扩展类如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
