prepare obs script for Holography map JUL
We have this old script https://gitlab.com/narit-raoc/tcs/tnrt/-/blob/main/scripts/test_ScanMap_BackendHoloFFT.py?ref_type=heads , but I'm not sure if it is updated to use the latest config parameters for BackendHoloFFT
Review this script and prepare parameters for Holography first map obs end of July
