Merge remote-tracking branch 'origin/ru-parallel-beamforming-fix' into integration-develop-nr-2019w51

- total num of symbols is 12 instead of 14 in PUSCH
- actual UL slot is 3 instead of 2

Replace "slot == 18" by "slot == (20 + NR_UPLINK_SLOT - DURATION_RX_TO_TX) % 20".
At least this is correct for 30 kHz SCS...

- nr_ulsim supports multiple DMRS configurations

- added get_l_prime function
- added Table 6.4.1.1.3-3
- added added is_dmrs_symbol function
