updated calibration DTT templates 
I updated the swept-sine frequency vectors used in the calibration swept-sine DTT templates. They now match what is used in LHO's simulines configuration.

Frequency points changed (Hz): 

10.01 -> 10.11
59.78 -> 64.78
180.5 -> 175.5

DTT templates are located at /ligo/groups/cal/H1/ifo/templates. pyDARM cmd tools will automatically use these templates on future runs.

Reasons behind changes were to avoid the QUAD bounce mode; and steer clear of the 60 Hz line and its harmonics. These impacted the transfer function and coherence of the measurements.

I'll add that we're building the confidence to move completely over to simulines for future calibration injection suites. However, it's good to have the corresponding DTT templates kept up to date for the scenario in which they're needed.
