Update payload_id_list.txt

Change of my existing call signs to prevent confusion with APRS ssid's.

You need to be very very cautious changing existing payload IDs like this. At the moment I think of the payload ID list as mostly append-only.

All the stations running horusdemodlib won't automatically update their payload ID list unless either they see a new payload ID they havent seen before (and this is only in newer versions, and theres a lot of stations running old versions, or they get restarted.
This means that when you launch, you are going to end up with different stations uploading data with different callsigns. I think its going to be easier and safer for you to change your APRS SSIDs instead...

Thanks for comprehensive response! In that case I will change APRS SSID.
