Publish as a library

[klarkc]

Would you mind if we publish the client as a library? So I can re-use the type defintions and some functions in rowtype-yoga/purs-eval#3

I'd like to do that, but I'd prefer spago have support for monorepos first, so that we can publish the client as a library but still keep it distinctly separate from the other source code in this repo.
