adding N_RB_DL to nr_init_params, as it is needed in the gNB and the function is shared between gNB and UE. This should be revisited.

removing warnings for --emulate-rf mode, tx_frame now also written to binary file so that it can be read by UE in mode --loop-memory

removing reference to uesoftmodem from load_configmodule (don't understand why this dependence is there in fist place. Also makes unitary sims break)

Still a remaining issue with the SNR normalization, way too low to get errors.

0. unwiring of 40 MHz channel hard-coding and general SSB location
1. PSS dynamic range improvement and DC carrier fix
2. SSS channel estimation and detection corrected
3. PBCH channel estimation fixed
4. PBCH channel extraction/compensation reworked for the general case
5. fixed-point low-complexity polar decoder integrated to PBCH decoding chain

works by default (nr_pbchsim) at 100 MHz / 30 kHz SCS and SSB wherever (but known to UE)
