Adding noise in _step() function

Lines 1365 to 1372 in f0c2779

	pos, vel, rot, omega, acc = self.sense_noise.add_noise(
	pos=self.dynamics.pos,
	vel=self.dynamics.vel,
	rot=self.dynamics.rot,
	omega=self.dynamics.omega,
	acc=self.dynamics.accelerometer,
	dt=self.dt
	)

Why do we need this here? Adding noise is already done in state_vector() functions.
