fix the 64QAM modulator case, that process 192 bits per iteration, then 24 bits per iteration of the tail bits, then added the last two symboles processing (no odd number of symbols case)

* Lower scheduler PF averaging constant

This time constant plays a major role in how long a UE has to wait
maximally before it might be scheduled. For instance, if a UE had a lot
of traffic, the average traffic will be high, pushing the PF coefficient
down. If another UE with no traffic in the past becomes active with
heavy traffic, the first UE might not be scheduled for an extended
period of time.

In the AW2S-Amarisoft UE CI test pipeline, we sometimes see that the
maximum number of RLC retransmissions was reached. While this might not
be the (only) cause, scheduling a UE more often might prevent such
situations, and we saw an improved stability.
