As of now, H1:LSC-[XY]_EXTRA_AI_[123]_OUT_DQ are in the science frame at 2k, but nobody remembers what they are.

I went to the end stations and found that H1:LSC-X_EXTRA_AI_1 and H1:LSC-X_EXTRA_AI_2 were connected to green REFL A FET demodulator I and Q monitor. Same thing for Y.

Since we haven't looked at these for a long long time, I removed these cables from the DSUB breakout. There's still one cable attached to DSUB breakout which is for Ethercat-frontend interface, but this is not EXTRA_AI channel.

For the moment the output of these channels are turned off to compress the data size. Next Tuesday these are removed from the frame.

We'll also remove jitterFF signal from the frame as we're not using that feature.
