added optimized polar decoding to UE DCI processing. Still to be tested. Changed decoder API to return XOR(CRC,rxCRC) which can be used to check for RNTI at receiver. For PBCH it returns 0 on positive CRC, !=0 on CRC mismatch.

 -- in slave job, the lock is now properly done for the whole job
 -- in master job, all slave jobs are really sent in parallel
    they should now now appear as failed (if fails)

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
