Cabling corrections for IMC electronics (Jax, Kiwamu)

Over the past few days, we've been checking the cabling between the IMC electronics on ISC R1 and the EtherCAT CM Chassis.

Note: When I refer to slot numbers, I am using the convention used in D1001460. The racks on the floor are numbered using the opposite convention. After discussing with Filiberto, I have decided to relabel these racks later this week.

The relevant changes are between the VCOs and on the Mode Cleaner Servo.

Cable ISC_28 was attached to 79.4 MHz PSL VCO in slots 23-24, and was moved to its correct location at the 79.4 MHz ALS VCO in slots 32-33. The 79.4 MHz PSL VCO is intended to be attached to cable ISC_2. This cable is the wrong gender and will be changed in the near future. 

The mode cleaner servo had Cable ISC_6 in Controls 1, and Cable ISC_5 in Controls 2. The cable pull table did not make a distinction between Controls 1 and Controls 2 for this cabling. After checking the pinouts and cabling, I determined that cable ISC_5 needed to be in Controls 1, and cable ISC_6 needed to be in Controls 2. I made the change today.
