It sucked. The new one is using Sans I/O principles, so it does not
directly do I/O or talk to a net.Socket directly (instead, QemuVM implements
the layer to do I/O). This means in the future this library could actually
be tested, but for now, I'm not bothering with that.
There's also some other cleanups that were bothering me.
doesn't really need to be two seperate libraries. also preperation for other funnies
the build script has been replaced with a much saner justfile which uses much saner "yarn workspace" invocations instead of blindly cding all over the place
