Adding a test "framework" to run real world machine tests

[Torxed]

Because we have nothing, I'd like to have something. And this does something.

It runs qemu with test parameters. It has a test class that can take qemu serial output and manage it.

It can cycle through the menu's and handle triggers and monitor things. It's just one test case, it needs more - and it needs to be able to run multiple tests most importantly.

Working on pushing the .github/.gitlab* runner files for this, which will automatically publish the .cast recording of the output.
