Camera parameters should be float instead of int (return of pyflex.get_camera_params)

[TMats]

Hello developers!
Thank you very much for the active developments!

Since the camera parameters (position & rotation) are float, I think these lines are buggy,

softgym/PyFlex/bindings/pyflex.cpp

Lines 840 to 854 in bb383f6

	py::array_t<int> pyflex_get_camera_params() {
	// Right now only returns width and height for the default screen camera
	// yf: add the camera position and camera angle
	auto default_camera_param = py::array_t<float>(8);
	auto default_camera_param_ptr = (float *) default_camera_param.request().ptr;
	default_camera_param_ptr[0] = g_screenWidth;
	default_camera_param_ptr[1] = g_screenHeight;
	default_camera_param_ptr[2] = g_camPos.x;
	default_camera_param_ptr[3] = g_camPos.y;
	default_camera_param_ptr[4] = g_camPos.z;
	default_camera_param_ptr[5] = g_camAngle.x;
	default_camera_param_ptr[6] = g_camAngle.y;
	default_camera_param_ptr[7] = g_camAngle.z;
	return default_camera_param;
	}

So, the return should be py::array_t<float> instead of py::array_t<int>?

Thanks!
