Example: Parsing bytes into an Envelope

An Envelope represents the information you can get from an email's headers and body structure. Addresses in To, From fields etc are parsed into Address types.

```rust use melib::{Attachment, Envelope};

let rawmail = r#"From: "some name" some@example.com To: "me" myself@example.com Cc: Subject: =?utf-8?Q?gratuitouslyencodedsubject?= Message-ID: h2g7f.z0gy2pgaen5m@example.com MIME-Version: 1.0 Content-Type: multipart/mixed; charset="utf-8"; boundary="bzzbzzbzz"

This is a MIME formatted message with attachments. Use a MIME-compliant client to view it properly. --bzz_bzzbzz

hello world. --bzzbzzbzz Content-Type: image/gif; name="testimage.gif"; charset="utf-8" Content-Disposition: attachment Content-Transfer-Encoding: base64
