Display functions

[Ursescu]

Implement the display functionality. The changes must be in display.h, display.c, display_task function in main.

• [ ] Propose the struct representation of data to get from FreeRTOS queue inside display_task.
• [ ] It should fetch the data from queue and display them.
• [ ] Also, an abstraction layer can be implemented, in order to easily change the endpoint (multiple display support ?).
