SR LC tz saturating for wrong setpoint

Today, during normal alingment procedure with the new alignment interface, the local controls of the SR payload opened. When recovering the control loops, TZ was not closing properly as the LC was saturating all the time. This happened since the loop was trying to bring the tz to a wrong setpoint far away from the current mar TZ position. The change of setpoint in SAT_MAR_TZ_SET (and also in tx and ty) occurred during the use of the new UI (around 7.30 UTC, fig.1).

Somehow the correct values of the LC SETs have been overwritten with older values.

Correct numbers have been put and saved in the DSP card.

SR LC loops closed.
