Convert to clap (4.x) derive

[jrop]

This PR takes advantage of more statically known type safety for CLI argument parsing, making use of clap's derive feature. I prefer this over so-called "stringly-typed" code, as less runtime checks have to be performed: i.e., there are notably less .unwrap()'s and if-guards for things that clap can check for automatically.

I didn't see that #32 already exists-- So feel free to close this in favor of that one!

I'm probably gonna close this so #32 can stay open like you said @jrop just because it was opened first. Thanks a ton for the work regardless though!

If you're still wanting to contribute code somehow, the Rust code in makedeb is still awaiting a TOML parser to be written in it. I planned on getting that done shortly, but if you'd want to tackle it on I'd be more than fine with that. There's also some commands that need to be added to Mist still if you'd want to look at those in the issues.

Regardless, thanks a ton for the work, it's really appreciated! :)

@hwittenborn That sounds interesting. Do you have more info regarding the needs of the TOML integration in makedeb? Perhaps we can continue this conversation on Matrix if that is more conducive (@jrop:matrix.org)

[hwittenborn]

Yeah that sounds great - You're in the makedeb Matrix rooms already, right? If it's fine with you, we could just talk about it in #makedeb-project:hunterwittenborn.com.

I'm at school right now so I won't be able to do too much talking, but if you just want to ping me in there I'll respond right when I get the chance.
