Separate the binary and library

This uses the workspace feature of cargo, with the benefit that

1) We can more cleanly group the binary (user facing) code from the
   library
2) We can have dependencies that apply to the binary only

The first point could've been achieved without workspaces (Cargo
supports both binaries and libraries in a crate), but the second point
is what really makes this approach a lot better.
