Load MIME from a StringBuilder

Demonstrates the Chilkat Mime.LoadMimeSb method, which parses complete MIME text from a StringBuilder and replaces the current MIME. The only argument is the StringBuilder.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: When the MIME text already lives in a StringBuilder — assembled in memory, or read and lightly edited — this loads it directly without an intermediate string copy. Its parsing behavior matches LoadMime; the difference is purely the source. For content that might include arbitrary binary bytes, use the BinData loader instead.
