Make scream  more resilient to delay spikes

Use the minimum queue_delay from the last two feedback when calculating average queue_delay. This decrease the chance of reducing reference window due to increased delay that is only seen in one feedback.

Also replace usage of queue_delay_dev_norm with DelayBasedCongestionControl::ref_window_scale_factor_due_to_avg_min_delay and DelayBasedCongestionControl::ref_window_scale_factor_due_to_latency_difference
Both are used similarly to the old queue_delay_dev_norm, but are calculated based on the minimum average min queue delay and the average
latency difference per feeedback.

This replace previous:
if (l4s_alpha < 0.0001)
   increment_t *= max(0.1, 1.0 - qdelay_avg / (qdelay_target / 4))
end
