Cryptic error message if GitHub token is incorrect

[starsep]

If you have leading/trailing space in token in config.toml (error in copy-pasting) i.e.

[github]
token = " TOKEN_HERE"

gitout

• will be able to get repositories information including private ones
• will crash when trying to clone first private repository it tries with cryptic error:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { code: -1, klass: 34, message: "too many redirects or authentication replays" }', src/libcore/result.rs:1188:5

If token is incorrect in the other way then gitout crashes when trying to get repos info with

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /usr/src/rustc-1.41.0/src/libcore/macros/mod.rs:15:40

More helpful error message would be appreciated.
My api token is 40 hex characters.
I am not sure whether one could assert token format as there are probably no long-term guarantees in GitHub API.
I would assume there should be some endpoint which allows for easy checking whether provided token is correct. I checked that https://stackoverflow.com/a/58572011 seems to ignore extra spaces, haven't tried GraphQL API.

Yeah this isn't great. For now there's zero error handling while core functionality is built out. Once more behavior is in place I'll start introducing anyhow for semantic failure messages and disable Rust's backtraces.
