Set a Multipart Part Body from a StringBuilder

Demonstrates Rest.SetMultipartBodySb, which sets the text body of the selected multipart part from a StringBuilder.

Background. A multipart request is assembled part by part: the part selector chooses the part being built, header fields describe it, and a SetMultipartBody method supplies its content. The request is then sent with a multipart send or full-request method.
