Similar work with klog19597.

Abstract:
I measured the TFs from GAS filters and made models.
Then, I made damping filter and edited the guadian (VIS_paramsBp.py) to engage damping from the guardian request.

Detail:
I measured the TFs of all DOFs of GAS filters.
Then, I made suspension models at FM10 (SUSMod_220127) of {SF,BF}_DAMP_GAS filter banks.
Figure 1 and 2 show the models overplotted on the measured TFs.
The models are based on the measurement results stored at /users/VISsvn/TypeBp/PR2/TF/Measurements/20220127/PLANT_PRM_STANDBY_{SF,BF}_TEST_GAS_20220127.xml.

Then, I modified DAMP filters for both AS filters.
After checking new damping filter works, I edited the guardian, and they are engaged by guardian at ENGAGE_GAS state.

Note:
A strage peak can be observed in the TFs of BF GAS but I have no idea where this peak comes from.
Currently, it takes 1.5 minutes to reach ISOLATED state with guardian from SAFE state, seems fine (fig3).
