Now that we've got the SPI in chamber and moving things along with beams (LHO:90621), it was time to make another run through the MEDM screens and infrastructure (last touched during the initial release of the screens LHO:90006) to make sure the signals flow as intented and the UIUX has everything it needs.

This morning we:
    - Added linked to the picomotor control to the overview
    - turned on inputs, outputs, and set gains to 1.0 to make sure IFO PDs were demodulated and producing a legit live contrast estimate with the amplitude and mean of the PD signals
    - turned on inputs, outputs, and set gains to 1.0 in any bank necessary to make sure optical lever QPDs SUM, PIT, YAW signals made it to the {PIT,YAW}_OUT_DQ channels 
    - added a first-guess low pass -- 4th order butterworth filter with 10 Hz corner frequency -- to the MEAN banks that filter the raw IFO PD signals (with the 4096 Hz beat note on it) to get the mean of the signal.

This needed several mods to MEDM screens that had some missing filter banks:
    in /opt/rtcds/userapps/release/spi/common/medm/
    - Addition of links to picomotor control screens 
         SPI_CUST_OVERVIEW.adl            committed to   rev 35342
    - Added missing HETPHA and HETAMP filter banks at the output of I/Q to AMP/PHASE conversion
         SPI_CUST_IFO_DEMOD.adl           committed to   rev 35337
    - Added missing CONTRAST Filter Banks, and changed the precision of the OUT16 displayed on the screen from truncated (for signals above 1) to decimal.
         SPI_CUST_IFO_MON.adl             committed to   rev 35338.
    - Quick resolution of long-standing bug with labels of banks in 
         SPI_CUST_OL_ISIOUTF.adl          committed to   rev 35336

All of the above settings have been committed to the h1spih23's safe.snap
    /opt/rtcds/userapps/release/spi/h1/burtfiles
         h1spih23_safe.snap               committed to   rev 35340
