I have updated PCB of the Open Simple Lidar.

I have routed and placed small motor board together with the main PCB of the lidar. Earlier that motor PCB must be produced separately, but now only one common PCB in needed to be produced.  Motor board must be cut from the main PCB before assembling the main PCB.

Also I draw some descriptions for assembling PCB.
