Move implementation source files to a conventional src directory
I think this attempt to be optionally header-only was misguided, particularly
installing source code to the system include path. Typically anyone vendoring
code just includes the repository and builds from there anyway.
This commit moves all the implementation code to a typical src directory (Don't
Be Weird).
I still think there is some value in simple "inline" deployment, but that would
be better achieved another way, like producing a single-file amalgamation that
builds anywhere, ala sqlite.
