demo: Move top level to library work
...
With Diamond, the design top level *must* be in the "work" library,
otherwise your project will be haunted with weird compile errors
that sometimes simply cause the build to fail with an arbitrary
error message, but can sometimes even lead to a straight-up broken
bitstream.
Real bad stuff, so let's move the stuff from our "design" library
to "work". That fixes it.

We need a different NLP timeout for RX than TX.
Also use a prescaler to improve timing.

Instead of having the user wait until the en-low was latched by
the core, let's just latch it internally.

Well, not really. This just makes it compile and work with VUNIT,
but it's not a real VUnit test bench. Will do that at some other
