Change the IFF for all tankers to make it more consistent with C/S

[Heidana]

Is your feature request related to a problem? Please describe.
Currently the IFF for thankers are set via the unit and pilot name e.g. "ARCO AR 203 #IFF:5322FR"
AR402 and 403 are using invalid codes 5318 & 5319 respectively.

Describe the solution you'd like
My proposal is to change the IFFs so it corresponds to the Tanker C/S:
AR101 ->5101FR
AR20X -> 520XFR
AR30X -> 530XFR
AR40X -> 640XFR

Describe alternatives you've considered
Alternatively only the 2 invalid codes can be changed to something else 5322 and 5323 for example.

Additional context
This will help the F-15E to interrogate and find the correct tankers much easier.
I can help with updating the ATRM brief if approved.

As of now work on the ATRM is on the backburner in anticipation of the building of a new training mission on the Kola map when it drops. Because of this, I will not redo all IFF codes, but I have changed the IFF codes for the invalid codes of the two tankers AR402 and AR403

New codes:
AR402: 5322
AR403: 5323

@132nd-Entropy
When I changed the names per this request, I did not update it in the script(s). It has been reported on a couple events now that the tankers are not spawned, and I just now realized this is because I made this change in the name and not the script.

Are you able to help out with updating the name in the correct scripts? (I am not quite sure which/where to make the necessary change)

[132nd-Entropy]

sure ofc
