 * Clean Nozzle Feature -- EXPERIMENTAL
 *
 * Adds the G12 command to perform a nozzle cleaning process.
 *
 * Parameters:
 *   P  Pattern
 *   S  Strokes / Repetitions
 *   T  Triangles (P1 only)
 *
 * Patterns:
 *   P0  Straight line (default). This process requires a sponge type material
 *       at a fixed bed location. "S" specifies strokes (i.e. back-forth motions)
 *       between the start / end points.
 *
 *   P1  Zig-zag pattern between (X0, Y0) and (X1, Y1), "T" specifies the
 *       number of zig-zag triangles to do. "S" defines the number of strokes.
 *       Zig-zags are done in whichever is the narrower dimension.
 *       For example, "G12 P1 S1 T3" will execute:
 *
 *          --
 *         |  (X0, Y1) |     /\        /\        /\     | (X1, Y1)

 *
 *   P2  Circular pattern with middle at NOZZLE_CLEAN_CIRCLE_MIDDLE.
 *       "R" specifies the radius. "S" specifies the stroke count.
 *       Before starting, the nozzle moves to NOZZLE_CLEAN_START_POINT.
 *
 *   Caveats: The ending Z should be the same as starting Z.
