Read the REST Response Body into a StringBuilder

Demonstrates Rest.ReadRespSb, which reads the response body as text into a StringBuilder, replacing its previous contents.

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.
