Adds smoothness as a optional key to TIGER roads

Hey Kevin, thanks for your work on this. Can you describe what you've done here and provide some of your rationale? On its face, I'm a little skeptical that smoothness can be ascertained without having actually been to the road, and my working assumption is that TIGER King is mostly an armchair mapping tool.

Hi @whubsch thanks for your work on the tool! I don't know how others are using it but the first thing I did was go to my own area that I know well and started chipping away at things. To me (and others with a similar workflow) I know the streets pretty well and can give a good approximation of smoothness. But I can see that being a bigger question if I choose a random location. Maybe a local toggle to show more options?

Ok, I'm inclined to make this accessible under the "advanced mode" setting, like we did with the track toggle. Can you update the PR to add that option there? You can look at commit 7a8ab41 -- when I added the track functionality -- as a guid; you'll need to access the store in src/stores/useSettingsStore.ts. Let me know if you need help. Thanks!
