WP12151 Correcting missing channels in SDF snap files

Dave:

h1susitmpi's OBSERVE.snap was missing 4 channels. Since its settings were identical to those in safe.snap, OBSERVE.snap was changed to be an identical symlink as safe.snap

lrwxrwxrwx 1 controls advligorts 65 Oct 22 10:11 OBSERVE.snap -> /opt/rtcds/userapps/release/sus/h1/burtfiles/h1susitmpi_safe.snap
lrwxrwxrwx 1 controls advligorts 65 May  2  2016 safe.snap -> /opt/rtcds/userapps/release/sus/h1/burtfiles/h1susitmpi_safe.snap
 

The HEPI models h1hpietmy, h1hpiham4, h1hpiham5 and h1hpiham6 had safe.snap files were all missing the same 9 channels (see attachment).

These channels were added to the safe.snap files. To test, each models' SDF was transitioned from OBSERVE to safe and back to OBSERVE.
