在 struct 中嵌套 jsonvalue.V 之后，json.Marshal 时指定 option 不生效

[Andrew-M-C]

playground:

package main

import (
	"encoding/json"
	"fmt"

	jsonvalue "github.com/Andrew-M-C/go.jsonvalue"
)

type myStruct struct {
	Ext *jsonvalue.V `json:"ext"`
}

func (s myStruct) MarshalJSON() ([]byte, error) {
	w := myStructWrapper(s)
	return jsonvalue.New(w).Marshal(jsonvalue.OptSetSequence())
}

type myStructWrapper myStruct

func main() {
	st := myStruct{
		Ext: jsonvalue.NewObject(),
	}

	st.Ext.SetString("1000").At("A")
	st.Ext.SetString("2000").At("B")

	const expected = `{"ext":{"A":"1000","B":"2000"}}`
	for i := range 2000 {
		b, _ := json.Marshal(st)
		if string(b) != expected {
			fmt.Println(string(b))
			fmt.Println(expected)

			panic(fmt.Sprintf("%d - diff!", i))
		}
	}
}

Fixed in v1.3.7.
