The type of MySQL query results differs from the actual ones

          >@gqcn你好，mysql字段类型int unsigned DEFAULT NULL时，查询后值类型为string，期望的类型是int

CREATE TABLE `test_table` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `number` int(10) unsigned DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

package main

import (
	"fmt"
         _ "github.com/gogf/gf/contrib/drivers/mysql/v2"
	"github.com/gogf/gf/v2/frame/g"
)

func main() {
	one, err := g.Model("test_table").One()
	if err != nil {
		panic(err)
	}
	id, _ := one["id"]
	fmt.Printf("id: %V\n", id)
	number, _ := one["number"]
	fmt.Printf("number: %V\n", number)
}

@ANG-LD 我在 #4107 解决了这个问题，但这个pr需要更多的时间进行review。
