gstlal_compute_strain:  added options use either kappa_tst or kappa_pu to compute actuation time delay, instead of handling the timing of the actuation stages individually.

New cmath element lpshiftfreq that reads in a complex stream and multiplies the phase by a constant without affecting the magnitude. This can be useful when a function whose phase is proportional to frequency has a known value at a particular frequency, and the user wishes to evaluate it at a different frequency.

 - bug fixes in lal_adaptivefirfilt
 - Implemented lal_adaptivefirfilt to correct for f_s and Q time-dependence
 - Added options to correct for complex kappas
 - Added EPICS bits to calib state vector

- change the way the name is constructed
- change the properties that are advertised
- based on my current understanding of how this is supposed to work

- based on my current understanding of how this stuff is supposed to work

- replace built-in algebraic model with the actual trigger distribution
  from all of O2, marginalized across the entire bank

gstlal-calibration:  New element lal_adaptivefirfilt that allows constrution of a time-dependent FIR filter with zeros, poles, gain, and a time advance/delay. For details, type gst-inspect-1.0 lal_adaptivefirfilt.

inspiral_extrinsics.py: make number of simultaneously queried points a class variable and remove njobs arameter for compatibility with reference OS

gstlal_compute_strain:  Modified smoothing of f_s and Q to produce better results. Began updating CALIB_STATE_VECTOR for O3.

inspiral_extrinsics.py: make it possible to read the snr dt dphi data from multiple files that have each only had part of the marginalized distribution computed

gstlal_inspiral_create_dt_dphi_snr_ratio_pdfs: optionally only create a subset of the marginalized dataset
