[core] increase max served tac/tai from 16 to 256

README.md

@@ -6,3 +6,6 @@ This is our (Althea's) branch of [open5gs](https://github.com/open5gs/open5gs).
 The `main` (default) branch contains our most stable version of open5gs, and is generally in active deployment by our team. `dev` and `hotfix` are sometimes used for rapid testing and deployment, but come with no guarantees w.r.t code stability or branch consistency (i.e. they could deleted).
 
 Tagged releases (e.g. `v2.4.7`) come straight from plain vanilla `open5gs` and can be considered a "starting off point" for our modifications. The corresponding branch with `_althea` at the end (e.g. `v2.4.7_althea`) is a tightly-curated (and sometimes rebased) branch that is designed to be easy for the open5gs community to read/follow. Whereas `main` might have multiple commits for a given feature as we expand utility over time and find/catch bugs, the `_althea` branch will have just one commit for a given issue.

+## Number of Served TAC/TAI
+open5gs has a limit of 16 different served TAIs hard-coded in OGS_MAX_NUM_OF_SERVED_TAI. Althea's KeyLTE architecture relies on many more than that: each edge KeyLTE router has its own TAC/TAI. We have currently set OGS_MAX_NUM_OF_SERVED_TAI to 256; this might increase again in the future.
