Load MIME from BinData

Demonstrates the Chilkat Mime.LoadMimeBd method, which parses complete MIME bytes from a BinData and replaces the current MIME. The only argument is the BinData.

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: This is the safest loader because it works on raw bytes: MIME can carry 8-bit content and even embedded NUL bytes that a text string would mangle, so loading from a BinData preserves the message exactly. Prefer it whenever the input is binary or of uncertain encoding — a downloaded message, a file read as bytes — over the string-based loaders.
