Optimize line subtraction median array length updates for high latency

See merge request Calibration/gstlal-calibration!6

lal_smoothkappas:  When element is reset with a truncated median array, take filter latency into account

Fix for pipeline hanging when run offline in high latency

See merge request Calibration/gstlal-calibration!5

calibration_parts.py:  Remove signal exists gate from line subtraction when filter latency is not zero

Fix PUM/UIM filter error when not applying TDCFs

See merge request Calibration/gstlal-calibration!4

Several changes to fix line subtraction when lines turn on and off

See merge request Calibration/gstlal-calibration!3

 - Stop subtracting signal when lines are off
 - Don't use GstController for line subtraction updates due to detection of secular changes in TFs
 - Simpler measurement of secular change in line subtraction TFs
 - lal_insertgap: new property open intervals to allow bad-data-intervals to be open or closed intervals
 - Distinguish between zeros and missing data in line witness channels
 - lal_property: fix for occasional segfaults
 - lal_smoothkappas: Use property reset_times instead of reset.
 - lal_stdev: Use property reset_times instead of reset.
 - lal_asd: allow for negative fft overlap.
 - gstlal_compute_strain: Option to use a line subtraction gate value, as opposed to a threshold, so that values larger than those that indicate lock (e. g., corresponding to calibration measurement times), can induce gating.
