Get an Alternative Body into a BinData

Demonstrates the Chilkat Email.GetAlternativeBodyBd method, which copies the contents of the Nth alternative body into a BinData object. The first alternative body is at index 0, and it should only be called when NumAlternatives is greater than 0. This example builds a message with plain-text and HTML alternatives and copies the first into a BinData.

Background: This is the binary counterpart to GetAlternativeBody (which returns text). Reading an alternative into a BinData preserves the exact bytes — important when a body part uses a binary or unusual transfer encoding, or when you intend to hash it or write it out verbatim rather than decode it to a string.
