Add `--tui-privacy-max-ttl` flag to hide host and IP details for low ttl hops about trippy

[c-git]

Really cool idea, is it a big step to make this configurable from within the application so like during runtime?

It could be done, but would would the UX be for entering the desired ttl value? A pop up with a number entry box? The only alternative I can think of would be to have keys to increase/decrease the privacy threshold but that feels like overkill for this.

I'm not opposed to those options but since I don't think it's something ppl will use often I'd not want to take up valuable hotkeys by default. I'd allow them to be set by the user if the so choose if we decide to go that route. Initially I was just thinking that it would be something that you could change in settings so you wouldn't have to close and reopen the program.

Added #771 to cover the possibility of changing some settings at runtime.
