H2 FMY OSEMINF filter changes
The H2:FMY_M1_OSEMINF_*_ filters were modified via foton to remove the high frequency components that added a 180 degree phase shift to the signal. This remedied the earlier confusion with the FMY sign conventions not matching the expected electronics sign conventions.

The foton file is now saved locally as:
/opt/rtcds/lho/h2/chans/H2SUSFMY.txt

A repository version was committed under:
/opt/rtcds/lho/h2/userapps/release/sus/h2/filterfiles/H2SUSFMY.txt

The coefficients were loaded into medm, then the H2:FMY_M1_COILOUTF_*_ gains were flipped for each individual OSEM.  The damping loops were checked by being closed and were confirmed stable.
