move allocation of UL_tti_req_ahead array from scheduling to start-up phase

  - center frequency changed
  - command line option for the ul freq scaling
  - freq offset not normalized

    - command line options for timing offset rate and frequency offset at Point A

    - some log messages enabled only in debug mode

- get the reported SINR value from the index
- use BLER vs SNR look-up table from dlsim simulation (BLER threshold 10^-3)
- add a flag at gNB from CML to activate AMC
- add additional SINR offset at gNB from CML, to apply to the reported value for DL AMC

Add SINR report reception at gNB side and set reportQuantity to "ssb-Index-SINR" in rrc_gNB_reconfig
