Hi,

I'm currently working on a traceroute historizer, that uses trparse to compare traceroutes with earlier runs and only save different ones.

I've decided to make some modifications to the code, adding windows support among others.

I've looked accros a couple of your commits, and noticed that you say that hops may not start with 1. Can you elaborate please ?

@deajan 👍

-f first_ttl
Specifies with what TTL to start. Defaults to 1.

Thanks for that ;)
Indeed I'll have to update my traceroute diff code to handle those cases.
Btw, I'll probably ask @lbenitez000 to take maintainership over trparse (if he does not want to invest more time) since it will be the basis of my https://github.com/deajan/traceroute_history project.

Are there any code changes other than this PR that you would like to see merged ?
