After the CAL-CS model upgrade to have highpass/whitening filters on the CFTD CTRL paths, I've installed whitening filters on the CFTD paths. This is the same as we did at LLO (see LLO aLOG 42961). This has to be installed on both inverse sensing and actuation paths, but does not need to be in the CFTD_DELTAL_EXTERNAL whitening bank. We will dewhiten in DTT.

These are installed in FM1 of the CFTD_DARM_ERR bank and FM1 for each of the CFTD_DELTAL_CTRL*_HP banks.

The design string is: zpk([0.3;0.3;0.3;0.3;0.3;0.3],[30;30;30;30;30;30],1,"n")
