Firmware Upgrade

V8.01.67 Optimize the 3 color light logic ,Optimize the encryption algorithm

Release notes: The latest version is 8.01.67; 8.01.67 is for RDC6442S. 8.00.67 is for RDC6442G. The difference between the RDC6442S and RDC6442G is little. RDC6442S support 2 laser heads and can locate the positon of laser heads according to the cutting task automatically. RDC6442G does not support that.
