Feedforward step of an integrate-and-fire neuron, computing a single step

\[\dot{v} = v\]

together with the jump condition

\[z = \Theta(v - v_{\text{th}})\]

and transition equation

\[v = (1-z) v + z v_{\text{reset}}\]

input_spikes (torch.Tensor): the input spikes at the current time step state (IAFFeedForwardState): current state of the LIF neuron p (IAFParameters): parameters of a leaky integrate and fire neuron dt (float): Integration timestep to use (unused, but added for compatibility)
