MR !1616 NR SA tutorials v2
MR !1620 nr_pdcp: nia1 implementation
MR !1622 CI: do not trigger tests if nothing is tagged NSA
MR !1623 Fix for ssb subcarrier offset in case of f<3GHz
MR !1606 code maintenance
MR !1568 Add undefined behavior sanitizer in build_oai, fix some errors
MR !1587 Dynamically build L2sim proxy

The previous version would trigger sub-pipelines (LTE-2x2, ...) if no MR
had the NSA tag (without a commit, etc). Of course, this would make all
pipelines subsequently fail (as not enough arguments, such as the
commit, were given). In this commit, we read the output of `jq` from
JSON, which will result in an empty list if no MR is tagged with the NSA
label (and the output in the console will be nicer as well).

We reuse existing code from eia1 for actual computation. Maybe not the most
efficient. To be revised if needed.

Some hacks in CMakeLists.txt were introduced to compile
phy simulators. To be removed at some point.

dirty workaround in LTE get_prb(): it is not good, but keep safe in memory instead of writing outside the range

Add basic SA test to RAN-Container-Parent

In the previous version, not all fields, and in particular the
`eNB_index`, were not initialized, leading to errors when they were used
(e.g., the PDCP code checks that eNB_index == 0).
