UNTESTED:
Wrote in Orlando. Attempting to rework manual mode routine and how it interacts with front panel switch.
1. Moved manual mode loop from startup routine to end of main loop;
2. Created functions for platformUpLoop, emergency depressurize loop, pressure measurement routine;
3. Cleaned up many variable names (e.g., offsetPressure ==> offsetPressure1) for consistency.
1. This fixes the pressureOutput() function. So core functionality works; manual mode does not.
1. Created several new minor functions (platformDrop, pressureDump, buzzer);
2. Created travelling dot for platformUp routine;
3. Getting closer on manual mode function. Now mostly user messages.
1. Finished cleanup of new ManualMode loop in main loop;
2. Can also access from menu and skip null pressure checks for a true diagnostic state.
Trivial changes in comments.
