IdHeader, ReceivedHeader, saveContent and more

Changes in this release:

• New header classes and parsing for the following types of headers:
  ** IdHeader: for Content-ID, Message-ID, In-Reply-To and References
  ** ReceivedHeader: for "Received", check out (https://mail-mime-parser.org/api/1.1/classes/ZBateson.MailMimeParser.Header.ReceivedHeader.html)[the documentation].
• Find a part by Content-ID, for example: $message->getPartByContentId('a part id');
• New MessagePart::getBinaryContentStream and saveContent (so you can $message->getBinaryContentStream() without it attaching charset conversion stream, and $message->saveContent() to save the stream as-is without charset conversion).
• $message->save() now also accepts a string filename to write to file
• Moved out charset library from stream-decorators and into its own mb-wrapper
• Renamed github zbateson/MailMimeParser to zbateson/mail-mime-parser and zbateson/StreamDecorators to stream-decorators

Add missing Microsoft charset codes

Add missing Microsoft codes as found in #79 and discussed/fixed in ddeboer/imap#270.
