IM4trans whitening gain adjusted

I noticed that IM4trans S1 and S2 channels were saturated, probably after the power increase (similar to the case for IMC WFS noted in entry 9094).

I adjusted the whitening gain down from 45dB to 36dB, which brought segments S1 and S2 down from the rails. IM4trans signal looks better now.
