Add new content types and refactor message writer

Introduced "multipart/mixed" and "multipart/related" content types in encoding.go and updated msgwriter.go to accommodate these. Adjustments made in related tests for these new types. Additionally, removed unnecessary print statements and improved multipart alternative parsing in eml.go.
