Need PSL-ISS_SECONDLOOP channels for H1

This is a follow-up to #4 (closed), as a reminder we need to add the following channels to the H1 configuration files whenever they are available in the science frames:

H1:PSL-ISS_SECONDLOOP_QPD_SUM_OUT_DQ
H1:PSL-ISS_SECONDLOOP_QPD_PIT_OUT_DQ
H1:PSL-ISS_SECONDLOOP_QPD_YAW_OUT_DQ
