Pucch2 polar rx: fix dynamic range
...
fixes the overflow issue in the PUCCH2 RX with 4+ RX antennas and 12+
bits (polar code format). The fix scales the polar decoding LLR
computation according to the number of RX antennas. The issue was clear
for 100 MHz 4 RX antennas. Even
nr_pucchsim -s -5 -q 8 -P 2 -b 12 -R 273 -z4 -n1000
doesn't converge to 0 BLER with increasing SNR. The issue didn't appear
in CI because of the bandwidth and antenna count limitations.

Avoid concurrent write while filling RX/CRC.indication
...
We observe these asserts while running concurrent UL traffic on many
UEs:
Assertion (crc->rnti == rx->rnti) failed!
In handle_nr_ulsch() ../../../openair2/NR_PHY_INTERFACE/NR_IF_Module.c:193
mis-match between CRC RNTI 7221 and RX RNTI 35cf
CRC and RX indication need to be pairwise for one UE, when here we have
each for different UE. However, investigation seemed to indicate that
both arrays for CRC and RX indication contained only one PDU; it seemed
the RNTI changed while writing the CRC/RX.indication messages in
nr_fill_indication().
In this patch, we change the logic to mark a ULSCH free AFTER calling
nr_fill_indication(). It is difficult to say if this makes the assertion
disappear, but preliminary tests did not exhibit the same failure
states.
Closes #773

Add a generic function for tx write out of order (timestamps not increasing)
...
Add an API to allow out-of-order writes to a radio interface, unlike the
current interface.
this function is called in UE in this commit, even if the tx might
still be in order.
Later, i plan to improve UE pulti-threading, that will lead to out of
order tx. also, the gNB will benefit of this new function to replace
several specific pieces of code that reorder tx with over complex and
slow systems
