Pug caused no end of issues and is frankly far too heavy-weight for
what I want.
As it turns out, there are posthtml plugins to do everything pug did
for me, so it's getting kicked out.
Webpack was entirely and utterly unmaintainable. This commit throws it
out of the window into the gutter where it belongs, and rewrites the
entire repository so that it may work with parcel instead.
