APER encoding fails when using the asn_uint642INTEGER function on a 32-bit machine as shown below.
```C
asn_uint642INTEGER(AMF_UE_NGAP_ID, 0xffffffff);
...
aper_encode_to_buffer(...)
```
INTEGER APER encode/decode functions seem to be operating internally with long variables instead of intmax_t.
That is probably the reason of the failure.
@v0-e fixed this issues in the mouse07410/asn1c pull request.

Most of the time, an application wants to perform some amount of data buffering
in addition to just responding to events. When we want to write data,
for example, the usual pattern runs something like:
1. Decide that we want to write some data to a connection;
put that data in a buffer.
2. Wait for the connection to become writable
3. Write as much of the data as we can
4. Remember how much we wrote, and if we still have more data to write,
wait for the connection to become writable again.
Now, Open5GS implements the above method by default when transmitting data
in a stream type socket.
