SUS QUAD L1, L2 CoilOutF filter module updates

Modifications to the QUAD L1 (UIM) and L2 (PUM) stage CoilOutF filter banks were made via Foton to reflect the latest State Machine Diagrams updated last week.

The changes were saved to the filter text files, and filter coefficients were loaded via the "*_GDS_TP" medm.

The Foton filter text files were committed locally to the "cds_user_apps" Repository checked out under:
'/opt/rtcds/userapps/release/sus/h2/filterfiles/H2SUS*TMY.txt'

The ITMY & ETMY M0&R0 top stage CoilOutF filter modules matched the State Machine Diagram for the TOP Coil Driver before making modifications on the lower stage filter modules.

All filter modules for every ITMY,ETMY M0&R0 CoilOutF filter modules are identical and contain the following digital filters:
