Missing Job Token from PollResponse

[stutwoby]

On the documentation we're able to specify a job token that the server responds with. The printer saves the job token in volatile memory and passes it up in the next job. See documentation here:

https://star-m.jp/products/s_print/CloudPRNTSDK/Documentation/en/developerguide/pollingserver/post_jsonresponse.html

Currently when I try to respond using the utillities PollResponse object, it doesn't contain JobToken, I've started using a class that inherits and includes the new field:

    public class PollResponseWithJobToken : PollResponse
    {
        public string jobToken { get; set; }
    }

It would be nice to have this included.
