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

TTI is made. Instead of generating one CC in each dl_sched()/ul_sched()

With this PR, the srsenb rrc updates the phy_cfg before the ho cmd is sent, but, in the case of intra-enb ho, the updates are not submitted to the phy before the reception of the crnti mac ce
