Hey, Niklas Eklund and zimoun

Since you are the original contributors to =emacs-git-email= and
=emacs-piem=. Here are some changes you may need to be aware of.

I've split the package into multiple separate packages. So the user wants
=git-email-notmuch= or =piem-notmuch= don't have to populate there
home environment with =mu= and other dependencies.

Can you kindly review the changes, and give your thoughts on them?

Thanks
