Ratatui migration

[Pazl27]

Finally did the migration to ratatui :)

Thanks to RaphaelHerbepin for giving me the push to do this with his pr.

I also added some small new features:

• improved CLI help command
• added support for themes (ships with themes) themes get defined in separate config file
• change settings inside the TUI
• open stats page from the TUI

Glad I could help!
Great job on the result, I really like the menu navigation; it’s very user-friendly.
Maybe the next features you could use from my code are the advanced statistics, which might be interesting, as well as the ability to quickly restart the speed test using the various shortcuts (MonkeyType or 10FastFingers) that I implemented.
Great job anyway, can’t wait to see what you’ll do next! 💪

Oh yeah the advanced statistics sound very good, I have to take a look at that.
I also started with a new feature that allows you to use codesnippets for the typing test
