fix: reset terminal on panic

[AndrianoTurner]

Addresses #58.
Removed std::process::exit(1) in favor of returning Err(e).

Thanks for the PR.
I think that wouldn't be enough actually.
You need to reset the terminal so you need to to catch when the app encounter the error and run tui.exit() then exit.

Will look into it

tui.init()?;

When this is called, the panic_hook is set, so i think the panic!() macro can be used when we encounter an unrecoverable error.

Currently when iwd is not running and the following code is executed:
https://github.com/pythops/impala/blob/944ad007ec8d02b13d410a186131b29c4b953f4c/src/main.rs#L32C4-L38C1
it returns true and the terminal resets because tui.exit() is called (which is what i wanted to fix).

So should i replace all std::process::exit() to panics which will call the panic hook, or propagate the errors?

I think it is easier just to propagate the error and call tui.exit()? in main.rs
