BBPD swap for REFLAIR_B

BBPD S1200234 has been replaced with BBPD S1200247 on the ISCT1 table. This will be our new REFLAIR_B.

Daniel has modified #247 by removing the MAR-6SM amplifier. From Koji's measurements (LHO#14901), we expect this to increase the IP2/IP3 of the amplifier chain and therefore lower the intermod products in RF27 and RF135.

The dc readout should be the same (i.e., we expect to read out ≈ 27 mW from the PD), but the rf readouts should be reduced by a factor of 10 in amplitude.

After installing, I resteered the beam (both in pitch and yaw) onto the PD using REFL-M3.
