Test against the die-level simulator

[kosarev]

Goran Devic @gdevic, the author of https://github.com/gdevic/Z80Explorer, has just kindly told me that we have https://github.com/hoglet67/Z80Simulator -- a Linux port of a simulator originally written by Pavel Zima that makes it possible to literally execute die images of the original Z80 chip. I find both the explorer and the simulator completely mind-blowing projects, which I'm sure we can benefit from in a number of ways.

$ ./Z80_Simulator Z80
