Get a Related Item as Text with CRLF Line Endings

Demonstrates the Chilkat Email.GetRelatedStringCrLf method, which returns the text of a related item with CRLF (\r\n) line-endings, interpreting the item's bytes using the supplied charset. It is intended for text-based related items such as style sheets. This example reads an embedded CSS style sheet with normalized CRLF line endings.

Background: Embedded text may arrive with any style of line ending — bare LF, bare CR, or CRLF. This method normalizes them all to CRLF, which is what internet protocols and many Windows tools expect, avoiding mixed-newline problems when the text is written out or re-transmitted. It is the CRLF counterpart to GetRelatedString (which uses bare CR).
