This allows us to load them via doom-require. Why not use normal features? Because Doom's libraries are designed to be loaded as part of Doom, and will openly rely on Doom state if needed; this is a contract I want to enforce by ensuring their only entry points are through `doom-require` or autoloading. I will add them to the rest of the libraries later. Site-node: this also adds Commentary+Code to the comment headings, as I want a space to use that space to describe the library, when I get around to it.
