      Fix TPMI for UL retransmissions
      
      If the ul_ri of srs_feedback changes between a UL transmission and a
      retransmission, we use the TPMI of transmission.
      
      Closes #879
      
      Assertion ((*nrOfLayers==1 && srs_feedback->tpmi <= 1) || (*nrOfLayers==2 && srs_feedback->tpmi == 0)) failed!
      In compute_precoding_information() /home/user/openairinterface5g/openair2/LAYER2/NR_MAC_COMMON/nr_mac_common.c:2896
      TPMI 1 is invalid!

      Fix and refactor channel average
      
      - Fixing missing init average variable with zero and refactor the code #86b11ab7
      Fixes just the missing avg1=0
      - Refactor the code to a common SSE/AVX2 inline function using also horizontal add.
      - We use int64_t result from now on.
      - We decided to fix length to x12 instead of old x9 openair1/PHY/NR_UE_TRANSPORT/dci_nr.c

      Optimize PHY_ofdm_mod CYCLIC_PREFIX in case of incidentally aligned pointers
      
      It seems that the cyclic prefix is in most cases a multiple of 512 samples.
      This means that in most cases the idft output pointer is already aligned and
      there is no need to perform an extra memcpy. This saves the memcpy time in
      most cyclic prefix insertion cases.

      A script to run CI tests locally.
      
      Added ./run_locally.sh script. The script takes one argument being the testcase
      that one wants to run. The testcase is run locally. This means that some
      testcases that utilize hardware resources will not run. However most if not all
      rfsimulator testcases should run as in CI.
      
      To this end, the CI python scripting framework was updated:
      - override  and <srv_node> elements from XML so all commands are executed locally
      in case --local flag is passed
      - Allow RemoteCmd class to run on localhost

      Replace AssertFatal with static_assert for cmdline arguments check
      
      Replace AssertFatal with static_assert for command line arguments definition
      length check. The static assert will not allow the code to compile in case
      the size is incorrect.
      
      This could save some time in the future since its easy to forget to extend
      CMDLINE_PARAMS_CHECK_DESC.

      Change alignment of temporary IDFT buffer in PHY_ofdm_mod · 55b5e04e
      Bartosz Podrygajlo authored
      Alignment of temporary IDFT buffer was changed to 64 bytes. This is in preparation
      for possible use of different IDFT implementation which could use AVX-512, requiring
      64-byte alignment.
