TPOT packet ids.

note: TPOT only uses 2 packets. For early runs (before 07/28/2023) they are 5000 and 5001 For later run, (after 07/28/2023) and because, as instructed by Martin, they are 5001 and 5002 We keep all 3 values here in order to be able to read both type of runs One might need to change this in the future when 5000 becomes used by a different subsystem
