`SharedDispatch` type is not accessible

[Luro02]

I can call fern::Dispatch::into_shared, but when I try to return it from a function:

fn setup_logger(output: fern::Output) -> fern::SharedDispatch {
    let shared = fern::Dispatch::new()
        .into_shared();
    return shared;
}

I get an error.

error[E0412]: cannot find type `SharedDispatch` in crate `fern`
   --> runner\src\main.rs:279:49

For more information about this error, try `rustc --explain E0412`.

The type cannot be clicked on in the docs as well:
https://docs.rs/fern/latest/fern/struct.Dispatch.html#method.into_shared

I guess one has forgotten to export the type?

@daboross Python guy here practicing my hand at Rust would like to take a stab at this and submit a PR for a fix.
