removing some prints, changing phy-test mcs=0, disabling parallelization over segments (ldpc has not yet been integrated with that)

Merge branch 'RU-RAU-split-parallel' of https://gitlab.eurecom.fr/oai/openairinterface5g into RU-RAU-split-parallel

added numerology paramter

removed "short_offset" code from normal_prefix_mod. removed static declaration in PHY_ofdm_mod which was a cause for problems when parallelizing FFTs for FEP TX.

- change target values
- change upper/lower limit to trigger a tpc
- don't use ul_cqi from SR

The value of ul_cqi is not convincing, for both PUSCH and PUCCH,
more work/analysis is required.

put pucch metric into uci->stat before calling harq_indication. Fixes an issue with PUCCH1 SNR measurements coming from HARQ.

added deactivation of ULSCH harq process after 3rd retransmission. Avoids problem of accumulating failed RA processes.

Adjustment for received power calculation in eNB pusch procedures. Added factor to account for mcs (mimic the power control adjustment in UE).
activated periodic trace for PHR/PUSCH SNR/PUCCH SNR in MAC.
