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
