AZDelivery 2-Channel Relay Module Case

Modified the case by zer0flag to fit the AZDelivery Relay module I bought: https://www.amazon.de/AZDelivery-2-Relais-Optokoppler-Low-Level-Trigger-Arduino/dp/B078Q326KT

Now uses M2 screws inside the case to fasten the board to the case, as I couldn't fit the head of a M3 screw. On the outside M3 screws are still used to fasten top and bottom half together.
