EY green WFS DC centering (Keita, Daniel)
These are working again. We needed to align things on the table, as it was previously done with some random alignment.
The filter gains are +500000 counts for WFSA PIT/YAW and WFSB PIT, but -500000counts for WFSB YAW.
UGF is 10-12Hz for WFSA and 8Hz-ish for WFSB with these gains.

We are using a significant amount of the available range (±16000).
