feat(aspen/emacs): Begin a complete emacs config revamp

I'm still on doom, but without all the cruft I've accumulated over the
last ~6 years it's actually good and fast and nice. Also, the config is
literate now!

The old emacs is still in .emacs.d, since occasionally I want to
reference it, but eventually I'll just get rid of it
