A COTS UE is sending UE capabilities with accessStratumRelease "rel16"
which is not decoded by our RRC. Switching to RRC 16.13.0 lets our RRC
accept these capabilities (and as a positive side effect lets this
particular UE work nicely in NSA fr1).
We don't work much on asn1c. The version we use has several bugs.
There is an active community out there that fixes bugs and improves
asn1c. Let's use their version.
