* added fetch fmt server library * added first draft of matterhorn * added enum ReturnCode * added cpp TCP Interface to slsDetectorServer * added fmt to workflows * bug: added std::signal for proper handling of ctr+c * added compile option to set log level * WIP * dont use c project settings when building matterhornserver * updated logger * WIP * WIP * linked fmt to slsProjectOptions * solved merge conflict * some refactoring * cleaned up logs * added fmt to workflow * WIP * generated register defs from csv file * oops given in hex * properly added fmt as a dependency * add fmt to conda recipe * some format changes * dont use public headers of fmt * WIP * used CRTP for virtual detector * WIP * added udp functions to matterhornserver * Matterhorn in tostring * warning unused variable from other PR * fixed build * updated cmake * added Server class usable for all detectors * removed stopserver * added some more functions * wrong overload * porper cleanup of matterhorn app * PR Review * refactored directory structure * used pause insetad of sleep --------- Co-authored-by: Dhanya Thattil <dhanya.thattil@psi.ch>
