support OnBeforeResponse

[PeterYangs]

package main

import (
	"errors"
	"github.com/go-resty/resty/v2"
)

func main() {

	client := resty.New()
	
	client.OnBeforeResponse(func(client *resty.Client, response *resty.Response) error {

		if response.Size() > 1073741824 {

			return errors.New("file is too big")
		}

		return nil

	}).R().SetOutput("/path/123.zip").Get("http://www.ooxx.com/123.zip")

}

I want to determine the size of the content before parsing the Response, and throw an error if it exceeds my preset size.
