DPI Fault Object implementation

[atimin]

We need to read faults from PowerFlex 525 VFD by using DPI Fault Object.

Implementation

• [x] add all vendor-specific Objects in special namespace vendors. For Rockwell Automation the namespace will be vendor::ra
• [x] implement DPIFaul Object in the same way as other objects Identity, Parameter, etc
• [x] implement DPIFaultManager that provides a handle method that will check faults and generate a callback where you can process the faults.

Example

DPIFaultManager manager;
manager.setNewFaultListener([](const DPIFaultObject& obj) {
    obj.getFullInformation().faultCode;
});

manager.setTrippedDeviceListener([](bool tripped) {
});

auto si = std::make_shared<SessionInfo>("172.28.1.3", 0xAF12);
while(true) { 
  manager.handleFaultObjects(si); 
  // don't forget to sleep a while
};
