Read the REST Response Body as a String

Demonstrates Rest.ReadRespBodyString, which reads the response body as text and returns it. It is called after ReadResponseHeader in the staged request model.

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.
