Add a Related Item from BinData by Content-Location

Demonstrates the Chilkat Email.AddRelatedBd2 method, which adds a related item using the binary data in a BinData object, addressed by Content-Location. The second argument specifies the filename, path, or URL used by the corresponding HTML reference. This example embeds an image referenced as logo.png.

Background: This is the binary counterpart of AddRelatedString2 and the Content-Location sibling of AddRelatedBd. Instead of a generated cid: reference, the HTML keeps an ordinary src="logo.png" and the related part is matched to it by name — convenient when turning an existing web page into an email so its original relative URLs keep working.
