@brief      TMTC Commander entry point for command line mode.
@details
This client was developed by KSat for the SOURCE project to test the on-board software but
has evolved into a more generic tool for satellite developers to perform TMTC (Telemetry and Telecommand)
handling and testing via different communication interfaces. Currently, only the PUS standard is
implemented as a packet standard.
