Dark processing and deployment

• epixm320_dark_proc -k exp=tstx00417,run=324,dir=/drpneh/data/tst/tstx00417/xtc/ -d epixm -o ./work -D
• dark run should have 3 steps for gains SH, SL, AHL
• raw (4-ASIC) panel shape: (4, 192, 384)
• constants are saved in repository (see location using command epixm320_dark_proc -h) per panel per gain range
• -D option combines gain ranges constants for pedestals, pixel_status, pixel_rms, pixel_min, pixel_max in shape (3, 4, 192, 384) and deploys them in the DB

Gain from charge injection

• TBD
