Add RelatedWriter and InlineAttachmentHeader to write multipart/related mail (e.g. images embedded in HTML and referenced via Content-Id). Entry points are CreateRelatedWriter (top level) and Writer.CreateRelated (nested); RelatedWriter offers CreateInline/CreateSingleInline/CreateInlineAttachment. - filename parsing extracted into a shared parseFilename helper (keeping the Content-Type "name" fallback) - every constructor copies the header (copy-on-write) Originally by BluePsyduck (emersion#181).

This PR adds support for multipart/related to the mail package by introducing a new
RelatedWriterand corresponding methods to the package. See #179 for more information about the usecases.This PR also renames existing functions and methods to make the wording more uniform. In detail, the following renamings have been added:
InlineWritertoAlternativeWriterto represent its task of writing "multipart/alternative", the same way like the newRelatedWriterwrites "multipart/related".CreateInlineWriter()toCreateAlternativeWriter()to match the renaming of the returned writer.Writer.CreateInline()toWriter.CreateAlternative()to match the renaming of the returned writer.The old namings are still in-place and marked as deprecated, so this PR does not introduce a BC break.
