Append capture file name with capture type, PMKID or HS

**Is your feature request related to a problem? Please describe.**
It should be more clear what type of info was captured in the PCAP, often running the conversion tools I don't know which one to use. If the PCAP has the PKMID or a handshake.

**Describe the solution you'd like**
Append capture file name with capture type, PMKID or HS.

ex. "MyWiFi-as2X2-PMKID.pcap"

Start by locating the capture-file creation and conversion entry points in the Python code, then trace how the PCAP filename is currently chosen. Confirm how PMKID and handshake captures are distinguished. Done means generated filenames clearly include the capture type, such as PMKID or HS, without breaking existing capture handling.
