Modified the script to get the OSEM estimators installed on PR3/SR3

I modified Oli's script  make_EST_model.m that gets the OSEM estimator filters into the front-end models. This script is now the preferred way to get any estimator model filters into the real-time computers. The change was made to add failsafes to avoid further errors on the translation of fitted filters into foton ( see LHO: 87689 ).

For the script to work, any .mat files with estimator filters must have the following syntax:

(sus)_est_model.(dof).(input_stages).(inputdof2dof) - For example
PR3_est_model.P.suspoint.L2P contains the zpk for the PR3 suspoint L to M1 OSEM P model.
 

The format for the filters can be seen in any of the .mat files listed below that live in (svnroot)/sus/trunk/HLTS/Common/FilterDesign/Estimator/. The files come with a README that indicates at how the fits inside were created

est_model_H1PR3_L_2025-10-07.mat  -- contains slightly tweaked versions of the PR3 L (and P) models reported in [LHO: 87593]
est_model_H1PR3_P_2025-10-07.mat  -- contains slightly tweaked versions of the PR3 P (and L) models reported in [LHO: 87593]
est_model_H1PR3_Y_2025-08-19.mat  -- contains the PR3 Y fits from [LHO: 86563]


est_model_H1SR3_L_2025-10-07.mat -- contains slightly tweaked versions of the SR3 L (and P) models reported in [LHO: 87612]
est_model_H1SR3_P_2025-10-07.mat -- contains slightly tweaked versions of the SR3 P (and L) models reported in [LHO: 87612]
est_model_H1SR3_Y_2025-08-05.mat -- contains the cleaned SR3 Y fits from [LHO: 86366]

These are the new .mat files that have the current OSEM estimator models. Until further notice, all previously existing .mat and .m files for OSEM estimator models/fits have been deprecated. We will later talk with Oli to standardize the addition of the OSEM estimator blends.

The updated make_EST_model.m, as well as the rest of the .mat files with the new syntax have been updated to the SUS svn under revision 12754.
