- Uses the asynchronous reading mode and the SmartingAmp
  class again as was likely originally intended
- Condition variable is used to wait on new samples being available
  so we don't busy-wait the CPU
- Fixed the thread joining
- Fixed several memory leaks
- Channel count is now fixed to 27
- Named the 3 gyro channels
- The driver now remembers the specified COM port
- KB entered COM port selection doesn't now need Enter key
- Removed latency/drift code that looked like adhoc hacks
