Extension connectors

Two 2.54 mm pitch headers CN4 and CN5 called "extension connectors" are intended to
connect an external board to the STM32L073Z-EVAL evaluation board.
Both connectors CN4 and CN5 give access to the GPIOs that are not accessible by the LCD
glass connectors.
In addition to GPIOs, CN4 and CN5 have the following supplies and signals:
GND, +3V3, D5V, RESET#, V
