Femtosecond timing analysis

LW61 (example)

Sequencer event codes in the DAQ:183: "Laser On"
179: "Laser Off"
137: "Every HXR Beam"
13: "Every SXR Beam
162: "BYKIK"137 will trigger Jungfrau readout. 13 and potentially 162 will be used for TimeTool calibration. The plugin, which records the delay between the optical laser and the x-rays, locates an edge on the time tool spectra. We calibrate this with a "laser on" but "X-rays off" i.e. 183 and 13 are TRUE

WIP: generate sequence with `~cxiopr/experiments/cxilw6120/sequencer.py` which pushes the sequence in the sequencer:

BYKIK

in cxi3: lcls.bykik_set_period(17)
