Fetch a MessageSet into an EmailBundle

Demonstrates the Chilkat Imap.FetchMsgSet method, which downloads the messages identified by a MessageSet and appends them to an EmailBundle. The arguments are headersOnly, the MessageSet, and the EmailBundle (which is not cleared). This example searches for unseen messages and downloads the whole set.

Background: This is the natural pairing with QueryMbx: search to get a MessageSet of matching identifiers, then download exactly those messages in one call. Fetching a set is far more efficient than looping one message at a time, and it returns an EmailBundle you iterate with MessageCount and EmailAt. Pass headersOnly = true to pull just headers for a fast preview list.
