Initial release for the TMTC Commander core.

It was refactored to be more generic and to be the basis for TMTC commander programs adapted to the need of other missions. A user folder was introduced and the contents of this folder can be copied manually to have a starting point for other missions. A lot of functionality was used from the SOURCE TMTC commander to the core and hook functions and enums were introduced to transfer configurable options to the user.
