Changes:
- Divided code into header files.
- Included "basicMPU6050" and "imuFilter" libraries to handle gyroscope and accelerometer.
- Added self-uprighting correction via accelerometer.
- Simplified RX signal interrupt routine to reduce servo jitter. Reduced interrupt conflicts.
- Added Alpha-beta filter to obtain derivative of gyro signal. Much smoother and lower noise output.
- Configured tail rotor output to command bi-directional ESC.
