Fixed up PRMI / DRMI locking

Jenne, Stefan

PRMI and DRMI lock acquisition was very sloppy the last few days, so we actually looked at the fringes, gains, trigger thresholds, etc. A number of tweaks were required:

REFLAIR_A_RF45 PHASE was changed from 142deg to 157 to minimize the I signal bleeding through.

PRMI acquisiton gains: PRCL 16, MICH 2.8

PRMI locked gains: PRCL 8 (nominal UGF 40Hz), MICH 2.8 (nominal UGF 10Hz)

DRMI locked gains: PRCL 8 (nominal UGF 40Hz), MICH 1.4 (nominal UGF 10Hz), SRCL -45 (nominal UGF 70Hz)

DRMI acquisition gains: same as PRMI: PRCL 16, MICH 2.8, and SRCL -30
