Reduce threshold for looking for ETM glitches
Currently, the etm_glitch script will find etm glitches if the glitch goes above 3e5 and then back below 1e5 within 60ms. It looks like this does not catch a fair amount of ETMX glitches though, so eventually we want to change this code to check for glitches based on a running standard deviation. Since that will take a bit more time to implement, for now, we are just wanting to reduce the THRESH value in etm_glitch.py (which gives the high threshold value that ETMX needs to surpass) to 2e5 or 1.5e5 so we can catch more of the glitches. It would also be nice if the ETM Glitch plot is made whether or not the glitch is found.
