Add LRSM v1.7 UFO model
Adding an updated version of the LRSM UFO model.
We need this model for preliminary studies for the ANA-EXOT-2024-03 analysis, the MC request was presented in EXOT meeting on 03/04/2024, link. The model will soon (1 or 2 weeks) be replaced by another updated version (when the theory contacts publish their paper) since this one includes some known bugs that do not affect our studies.
