This builds a very basic version of the nats.c client (no TLS, no streaming/jetstream/whatever, since those bring in complex dependencies and I do not need them at the moment). Right now it contains a simple test program that demonstrates the functionality (cool!), but the plan is for the nats.zig to bind the API into a nicer, zig-like shape and re-export it. Then this becomes a package. The current function could become a test, though it's a bit complex for a unit test (and requires connecting to an externally-running NATS server in order to work).
