Send a Staged REST Request from a StringBuilder

Demonstrates Rest.SendReqSb, which sends a request whose text body is read from a StringBuilder, 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.
