Valve control

- [ ] valves need to have the option of manual control. Either press [m] to enter manual mode then use the numbers to toggle each valve, or use numbers/arrow keys to select a valve and the space bar/enter key to toggle it.
- [ ] Need to have the option of storing and selecting different run configurations for different test types. This would manife4st as having more than one valve/state matrix system that could be selected. Would make sense to read these from a file
- [ ] Control of igniter at T-3s, should require button press before T-0 as visual confirmation of ignitor success
