Add tests for various email scenarios
This commit introduces tests for different email scenarios including emails with no boundaries, emails with attachments, emails with embedded items, and multipart mixed emails. The tests ensure that the code correctly returns all expected parts of the email (e.g., embeds, attachments, parts) and that it correctly processes the email subject.
