Remove anyhow, structopt from lib dependencies

[Urhengulas]

Hi @tmplt,

I'd appreciate if we could remove anyhow and structopt from the dependency tree of the library, since they are not required for it, but only the bin, as you also state in the Cargo.toml.

What do you think about this?

Of course. But apparently there is no easy way to separate bin/lib dependencies. See <rust-lang/cargo#1982>. An alternative is to split the crate in two, but I would prefer not to.

I see that this is a bit more complicated than expected and understand that you'd like to keep the crates combined. I will think about a approach and propose it here 😄

The crate shares the same name as the executable also, which may be cause for trouble (it already is when generating documentation locally). #8 would warrant a name-change on the crate.

So what do you think of the idea of hiding the deps behind a cargo feature bin. This feature is enabled by default, but as a library user I can easily get rid of them by setting default-features=false.

LGTM. Create the PR and I'll merge it.
