members.json request is not right

[Icedroid]

func (mg *MailgunImpl) CreateMemberList(s *bool, addr string, newMembers []interface{}) error {
    r := simplehttp.NewHTTPRequest(generateMemberApiUrl(listsEndpoint, addr) + ".json")
    r.SetBasicAuth(basicAuthUser, mg.ApiKey())
    p := simplehttp.NewFormDataPayload()
    if s != nil {
        p.AddValue("subscribed", yesNo(*s))
    }
    bs, err := json.Marshal(newMembers)
    if err != nil {
        return err
    }
    fmt.Println(string(bs))
    p.AddValue("members", string(bs))
    _, err = makePostRequest(r, p)
    return err
}

in the api document, no subscribed form value, you should change to same the api docuemnt. change subscribed to upsert。

p.AddValue("subscribed", yesNo(*s))
=>
p.AddValue("upsert", yesNo(s))

It looks like this has changed in the API and the library should be updated accordingly.
