Tool for nulling sensitive QMDL/PCAP fields

It would be great if rayhunter was able to null out sensitive fields (IMSI/IMEI) in a QMDL before storing them, which would make sending QMDLs around less of a privacy nightmare.

This could happen in-process if our telcom parser was equipped to serialize structs, but that's currently not the case. Instead, maybe we could use something like pycrate to make a python script that anonymizes QMDLs?
