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

enb_mac: pre-allocate UE object for quicker PRACH/RAR handling
...
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.
This patch pre-allocates one UE object that is then used
during the PRACH.
