@K-dash Thank you very much for the PR.
I double checked what to output looks like and realised that we might want the output to look different.

Previously

$ cargo run README.md -v

   [ERROR] Test
   [WARN ] Error creating request: InvalidPathToUri("/CONTRIBUTING.md")

     [200] file:///home/thomas/Projects/lychee/docs/TROUBLESHOOTING.md

As you can see, it seems like the initial intention was to align the closing brackets ], that is to align it to the right. I didn't realise this until now.

This PR

Proposal

Could you update the PR, so that the output looks as follows?

    [WARN] Test
    [INFO] Test
   [ERROR] Test
    [WARN] Error creating request: InvalidPathToUri("/CONTRIBUTING.md")

     [200] file:///home/thomas/Projects/lychee/README.md#features
     [200] file:///home/thomas/Projects/lychee/docs/TROUBLESHOOTING.md

Sorry for realising this only at this stage.
