Fix #680, implemented the command library for GAIA Boards (#686)

* Fix #680, implemented the command library for GAIA Boards

This command library only contains the bare minimum commands that are necessary to check the status of the hardware and some information of a GAIA Board, along with the command that turns on the Low Noise Amplifiers. The rest of the commands have NOT been implemented in order to prevent possible damage to the hardware controlled by the GAIA Boards

* Moved the GAIABoardCommandLibrary to the SRT section
