Disable Dolphin Calibration; Improve Example YAMLs

• Disable Dolphin's motion input gyro calibration - all calibration should be done on DorsalVR's end and Dolphin should take any inputs from DorsalVR at face value, so there's no need for Dolphin to do this calibration.
• WiimoteNunchuk.yaml now imports Wiimote.yaml (renamed from WiimoteOnly.yaml) to reduce redundancy
• ValveIndex.yaml overrides the default controls triggered by grip to use gripForce based on #5
