Violin damping settings which worked for 2W and 10W input power

This morning while Corey and the commissioning team were trying to lock and power up the interferometer, the violin modes were pretty rung up. For most of the modes, I was able to damp them down using nominal settings except three of them which are listed below along with the settings which seems to be working for now.

Made those changes for 2W damping, and will hopefully be able to confirm whether they also work for 60W. For ITMX 03 and ITMY 05, I added new 2W settings for IX3 and IY5. These changes were saved in lsc_params and the violin damping guardian has been reloaded.
