Send a Staged Multipart REST Request

Demonstrates Rest.SendReqMultipart, which sends a multipart request using the parts configured on the object, then reads the response in separate steps.

Background. The staged request model separates sending from reading: a SendReq method transmits the request, ReadResponseHeader reads the status line and headers, and a ReadResp method reads the body. This gives fine control over large or streamed messages compared with the single-call full-request methods.
