Dylan M. Taylor d4e3017c34 Add craft-mime: Internet message and MIME reader and writer (#814) ...

MailCraft and WordCraft each parse MIME: MailCraft for mail (crates/mime,
crates/charset), WordCraft for MHT web archives (formats/src/mht.rs). This
adds one shared crate for the format, taken from MailCraft's code where it
is format code, with WordCraft's multipart/related lookups and its fix for
comments in Content-Type.

Reader: parse() gives a tree of parts (header fields, content type and
parameters, decoded body, charset-decoded text). It never fails or panics,
is linear in the input, and is bounded by Limits (input size, header count
and sizes, depth, part count, decoded size); Message::truncated reports a
limit that left something out.

Writer: Entity::text / file / multipart and write_message, with folded
headers, RFC 2047 and RFC 2231 encoding, quoted-printable and base64 with
line limits, and boundaries checked against the content. Every header
value loses CR, LF and NUL, and a name that is no field name is not
written.

Also: address lists, mbox splitting and writing on raw message bytes, and
Date parsing and formatting on a plain struct (chrono is a private
dependency; no date type is in the public API).

No app is switched here. The README has the migration tables and says what
stays in the apps.
