* copied jungfrau server to moench and adapted * fixed image size and num packets * read n rows allows 16 * commneted out configure_asic_timer at server startup. To be removed later the ASIC_CTRL_REG and storage cell options * moench:removing the decrement (which was in jf) in read n rows to register * removed lblsamples from gui
