add hand.py/hand.ino used to create this VR glove, using MuJoCo Haptix MPL hand (Apache 2 license)

added b3InitSyncBodyInfoCommand, to retrieve body info, when connecting to a server with existing bodies
pybullet will call this b3InitSyncBodyInfoCommand automatically after connecting
Avoid overriding the py.setVRCameraState setting in VR
