Fix area calculation of Face3
There seemed to be a bug in area calculation in Face3::get_area()-function. It returned the area of "imaginary" parallelogram instead of the triangle. Therefore the area returned was twice the real area. This manifested itself when using a hydro module for godot ( https://gitlab.com/ringtechsolutions/godot-tools/hydro/hydro ) causing the buoyancy to be two times the expected value.
