Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

Francisco 94efeab672 Optimization of sched_ue methods to derive required number of prbs to allocate to a rnti

The number of iterations in the worst case scenario, reduced from 100 to 5 with
the proposed algorithm.

couldn't decrypt the first response of the UE on SRB1 that was
already encrypted.
