Function evosim::contorl::update::get_cf_signal

fn get_cf_signal(
    entity_id: Entity,
    cf_events_vec: &mut Vec<ContactForceEvent>,
    blob_flag_q: &Query<'_, '_, &ColliderFlag>
) -> Option<(bool, bool, [f32; 2], f32)>

Not a bevy system.

Output singal depends on NN’s input

collect contact force events and translate it into nn signals

contact blob and contact wall have different signal
