Parser v2 still cannot unmarshal correctly.

It's affecting SearchPublicChat and GetChat method.
Maybe it's same issue like #1

code:

chat, err := client.SearchPublicChat("tg_x64")
if err != nil {
    fmt.Println(err.Error())
    return
}

Error message:
json: cannot unmarshal object into Go struct field .last_message of type tdlib.MessageSender

Reason:
Since a public channel with linked group is allow an user reply without join group,
after SearchPublicChat, we can receive chat JSON like this

        "interaction_info": {
            "@type": "messageInteractionInfo",
            "view_count": 1,
            "forward_count": 1,
            "reply_info": {
                "@type": "messageReplyInfo",
                "reply_count": 1,
                "recent_repliers": [{
                        "@type": "messageSenderUser",
                        "user_id": 123456789
                    }
                ],
                "last_read_inbox_message_id": 0,
                "last_read_outbox_message_id": 0,
                "last_message_id": 1048576
            }
        }

But interaction_info do not have UnmarshalJSON method to handle multiple messageSenderUser, so go-tdlib can't parse correctly and return the error.
It's easy to reproduce on my example code.

Another cannot unmarshal method: SearchStickerSet and affecting all sticker method
json: cannot unmarshal object into Go struct field ClosedVectorPath.thumbnail_outline.commands of type tdlib.VectorPathCommand
