feat: Add initial CGNAT check logic

[GeckoEidechse]

Adds some logic that gets external IP and runs tracert to count the number of hops to said IP address. The goal is to have an automated way to check for CGNAT.

TODOs:

• Use -d arg to disable reverse DNS lookups (thanks @p0358 via https://discord.com/channels/920776187884732556/936105663942246410/1262421359271743488)
• Set max hope count arg
• Set timeout arg
• Also count lines with timouts. Currently hops are counted by checking if they contain ms (indicating ping time) but that skips hops that have a timeout and look like: 5 * * * Request timed out.

Worked for me in testing and locked behind dev view for now.
