Laser standards - update standards to standardize the standards

[CaptainBobSim]

Basically switch BLACK and RED. Black logically makes sense to be a cut so that's what I did (cut on the solid black line) RED instead should be cut BLUE should be engrave

• Use RED lines to indicate cutting.
• Use BLUE lines to indicate vector engraving.
• Use BLACK and other colors to indicate raster engraving. (Raster Engraving is not supported for DXF files.)
