OSEMINF compensation filters updated to match with satamp swap: ITMX (L1), ITMY (L1), BS (M2), PRM (M2, M3), SRM (M2, M3)

Fil swapped out the satamps for ETMY (L1), ITMX (L1), ITMY (L1), BS (M2), PRM (M2, M3), SRM (M2, M3) today (87103), so the 10:0.4 filters compensation filter in the OSEMINF bank for these SUS's named stages needed to be updated to their new precise compensation filters. Jeff measured the response for each satamp's channels before they were installed, and I used my script python3 /ligo/svncommon/SusSVN/sus/trunk/Common/PythonTools/satampswap_bestpossible_filterupdate_ECR_E2400330.py -o ITMX_L1 ITMY_L1 BS_M2 PRM_M2_M3 SRM_M2_M3 to mass update these compensation filters. I've attached a txt file of the output of this script, along with the filter diffs for each suspension before I loaded them all in.

PS Jeff had done ETMY L1 by hand earlier, so I didn't need to update it with my script.
