Add formatting fixes and remove dead code (debug_assertions)

[adamperkowski]

Did a few little formatting changes.
There is something like Rust FMT (an official tool, bundled in cargo) which helps you keep your code "clean". You can use cargo fmt --all --check to check your code formatting.
You can also add a GitHub Action that checks it (this one for example). Really can help write better code.

Also, you shouldn't really have dead code in your releases. I understand there's dead code when you're actively working on something, but you can always use debug_assertions or just comment it out so it won't be there when you run cargo build --release and release it.

[adamperkowski]

You can also use ex. cargo clippy for more lints (which returns one warning btw) but I'm leaving it out to you.

[adamperkowski]

This is not a conflict, this is a part of my PR. I have no way of resolving that.

Thanks @adamperkowski I'm still looking through the debug_assertions you added and seeing a few build errors. I made a couple commits trying to clear this up, but they still remain. I'll checkout this PR and see if I can troubleshoot further tomorrow.

fix build errors

[adamperkowski]

Sure. I'll update the branch and fix everything in about 5h. (it was not 5h)

EDIT: #55
