Siemens PRESETON/PRESETONS: Set actual value / without losing homing

PRESETON sets an axis actual value (absolute offset). PRESETONS does the same without losing the homed state.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.
