feat: Add serde feature

[nerdo]

Optionally allow verbosity flag to be serialized with serde.

Useful for when you want to easily save and load a configuration.

Hi! Thanks for your changes!

I think they can go in, but I'd like to see the one thing changed I annotated. No need to duplicate the #[cfg] attribute here 😆 I hope that's okay for you!

I disagree. I think more of a case is needed for why a CLI flag needs serialization, particularly the fact that this was done in a raw way (separate verbose, quiet as u8s)

I'm not sure what other use cases there are for serializing cli flags, but I think the clearest use case for me is the one I mentioned: saving and loading cli configurations.

That is what I'm using it for in my cli app. I proposed doing it as an opt-in feature with serde which is pretty ubiquitous.

The fact that they are u8's is a valid question. I would prefer it if at least quiet were boolean, but I didn't want scope creep - I just wanted to focus on being able to load and save configs and I found that when I added this crate, I could no longer do that.

I've been hoping to see this change so I can separate out my config from my args.

Progress seems stalled?

More design discussion is needed on this because exposing separate verbose and quiet fields that are u8 does not make sense.

As per my usual, I'd prefer those problem/solution discussions to happen on issues, keeping PRs focused on the implementation. Closing this until we have a design worked out. Feel free to create an issue.
