Fix for NTN phy-test mode

- Corrected the initialisation of ntn params changed flag. Before this change on
  UE, Phy-test was not running in NTN mode.
- Removed the assert wrt slot > 64 to run FR2-NTN in phy-test
- SIB2, 19 required only in SA mode like SIB1
- Introduced new method to schedule a slot in UL/DL in Phy-test mode. Dmod/ Umod
  option in the command line with a value.
  - This ensures that the slot n (in slots per frame) will be scheduled if
    n % value == 0
  - For ex: --Dmod 1 means every slot will be scheduled
  - --Dmod 2 means every 2nd slot will be scheduled, like 0,2,4,6 until the
    slots per frame 1.
  - this can be used for testing FDD FR2 where slots go beyond 64 which is a
    limitation of -D/-U option.

The OAI UE can also be used in front of a OAI gNB without the support of eNB or EPC and circumventing random access. In this case both gNB and eNB need to be run with the `--phy-test` flag. At the gNB this flag does the following
- it reads the RRC configuration from the configuration file
- it encodes the RRCConfiguration and the RBconfig message and stores them in the binary files `rbconfig.raw` and `reconfig.raw` in the current directory
- the MAC uses a pre-configured allocation of PDSCH and PUSCH with randomly generated payload instead of the standard scheduler. The options `-m`, `-l`, `-t`, `-M`, `-T`, `-D`, and `-U` can be used to configure this scheduler. See `./nr-softmodem -h` for more information.

- Options `-Dmod`, and `-Umod` were introduced to enable scheduling PDSCH/PUSCH on slots >= 64 in phy-test mode. (in case of >= 120Khz subcarrier spacing and FDD)
- For ex: `-Dmod 2' / '-Umod 2` allocates every 2nd slot for PDSCH or PUSCH respectively.
- See `./nr-softmodem -h` for more information.
At the UE, the `--phy-test` flag will read the binary files `rbconfig.raw` and `reconfig.raw` from the current directory and process them. If you wish to provide a different path for these files, please use the options `--reconfig-file` and `--rbconfig-file`.
