Measurement of an oblique edge (measurement type 16)

Measurement of an oblique edge ($AC_MEAS_TYPE = 16)
This measurement determines the position angle of the workpiece and enters it in the frame.
A setpoint angle in the +/- 90 degrees range can be input. This can be interpreted as the
resultant rotation of the workpiece after the result frame for the active WCS has been
activated.
