Andre Puschmann eea6f0f11b enb: fix potential invalid access in stdout metrics 
this fixes a potential access of invalid PHY or MAC metrics by checking
the user entry actually exists.

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
