A corner bracket for the Aqara FP2.

I wanted to cover my whole room with the FP2, unfortunately the FP2 can only see 120 degrees, for the whole room it should have been 180. So I decided to mount the sensor in the corner. To make this easier, I created this small mount together with @JoJohnJohnson_872770. Since I would rather not drill a hole with an anchor in my wall, I created a second version for nailing, just choose how you want to get the base on the wall.
