Ahmed Hussein 3a8bf560da channel estimation, compensation, etc .. 
Added the following folder:
- ../openair1/PHY/NR_ESTIMATION/

Added the following file to CMakelists.txt:
- ../openair1/PHY/NR_ESTIMATION/nr_ul_channel_estimation.c

Added the following functions:
- nr_pusch_dmrs_rx
- nr_gold_pusch
- nr_ulsch_channel_level
- nr_ulsch_channel_compensation
- nr_ulsch_scale_channel is commented out (I think only used for downlink)

Changes from Khalid Ahmed Mahmoud Mohamed:
- nr_pusch_channel_estimation is used
- nr_ulsch_scale_channel is used
- nr_ulsch_channel_level is used
- nr_ulsch_channel_compensation is used
- multiple logging options for channel and signal magnitude

Raymond Knopp d7c71252f0 nr_pbchsim: added -I option which runs initial synchronization. without, it just runs pbch decoding 
Still a remaining issue with the SNR normalization, way too low to get errors.

Raymond Knopp 8d78c0c98f Changes: 
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)
