Also change the `tester` package slightly to use an exposed `Registers` array rather adding yet another accessor method to retrieve a register value. This seems to me more transparent and "obvious" - we aren't trying to hide the fact that there's just a simple memory store there. Also unexport the `assertRegisterRange` method which was never intended to be part of the public API.
