Hashmap Marshal has some bug

[duruo850]

These codes run normally at times, but sometimes they throw errors： "not enough bits" ? why?

`package tonapiservice

import (
"fmt"
"testing"

"github.com/tonkeeper/tongo/boc"
"github.com/tonkeeper/tongo/tlb"

)

func TestHashmapE(t *testing.T) {
// Hashmap的序列化有bug，数据一样的情况下，有时候会提示not enouth bits.

c := boc.NewCell()
//write function id to cell
if err := c.WriteUint(uint64(0), 32); err != nil {
	panic(err)
}

type BuyInfo struct {
	StartLuckNum uint16 // 开始的彩票号码,从1开始
	Amount       uint16 // 购买的nifi数量
}

// go map
orders := map[uint32]BuyInfo{
	1: {StartLuckNum: 1, Amount: 2},
	2: {StartLuckNum: 3, Amount: 4},
	3: {StartLuckNum: 5, Amount: 6},
	4: {StartLuckNum: 7, Amount: 8},
	5: {StartLuckNum: 9, Amount: 10},
	6: {StartLuckNum: 11, Amount: 12},
}

type Msg struct {
	RoundId uint32
	Orders  tlb.Hashmap[tlb.Uint32, BuyInfo] // 订单号码:购买信息
}

// elb map
msg := Msg{
	RoundId: 10000,
}
var keys []tlb.Uint32
var values []BuyInfo
for key, value := range orders {
	keys = append(keys, tlb.Uint32(key))
	values = append(values, value)
}
msg.Orders = tlb.NewHashmap(keys, values)

// 序列化
if err := tlb.Marshal(c, msg); err != nil {
	panic(err)
}

b, _ := c.ToBoc()
fmt.Println(b)
