PH00524, but emulated

When troubleshooting the PH00524 evacuation controller board it's useful to be able to tell what the microcontroller should be doing, rather than just staring at disassembly/decompilation all day long.

This little program executes our scope evacuation controller's code (from the U12 EEPROM) in an environment consisting of a Z80 CPU and all peripherals required to reach a pumpdown state.

It comes with a little text UI interface:

Controls: [v] vent, [p] pumpdown, [q] quit
PC 02bc
---- -------- VENT
  M1     M2
|... ..

This shows the controls (keyboard buttons v, p and q), the last program counter at which an I/O operation was performed, indicator values, motor movement and lightbarrier status.
