Glitch model for O3a catalog events

Other Versions:
Glitch model for events in the O3a catalog that used BayesWave glitch subtraction. Each data file contains three channels:
1) the calibrated strain data, including any glitches that are present
2) a model of the glitches, produced using the BayesWave algorithm
3) the calibrated data with the glitch model subtracted, used for parameter estimation

For the L1 data for events S190424ao, S190513bm, S190514n, and S190924h, these channels have names
2) L1:DCS-CALIB_STRAIN_CLEAN_C01_glitch 16384
3) L1:DCS-CALIB_STRAIN_CLEAN_C01_T1700406_v4 16384

For the L1 data for events S190413ac, S190503bf, and S190701ah, the BayesWave glitch subtraction algorithm was applied multiple times to remove glitches. For these events the channel names are
1) L1:DCS-CALIB_STRAIN_CLEAN_C01_T1700406_v4 16384
2) L1:DCS-CALIB_STRAIN_CLEAN_C01_T1700406_v4_glitch 16384
3) L1:DCS-CALIB_STRAIN_CLEAN_C01_T1700406_v4_T1700406_v4 16384
