This patch adds the conf2uedata tool for generating .ue.nvram* .ue.emm.nvram* and .usim.nvram* files from a textual configuration file. The configuration file define most usefull values like plmns, mnc, mcc, msin, K, OPc for several users. The files generated will always ends with a number corresponding to the user entry in the configuration file. This breaks oai5g because other script have not be updated for using conf2uedata. This breaks also the at_nas_ue command. Examples of configuration files are in openair3/NAS/TOOLS/
