Two approaches to this occur to me:

1. extract the attachment, add it to the database and use normal reply
   processing (maybe remember to remove the message from the database
   after?),
2. hack something just in the emacs UI to generate a reply to the part.

The second is probably quicker to implement, but will side-step a bunch
of normal notmuch processing of the reply (whether this is important or
not I'm unsure).

The first seems “right”, but is perhaps invasive?
