Hello there, I have been really enjoying this tool, I came across it on reddit. I mentioned in the thread that I though that adding stats so you can see your max speed and accuracy would be good - and I have added that feature to my fork. I don't know if this is something that you would want to implement yourself, but in case it is helpful, I thought I would submit a pull request with my changes.

Here's a summary of the changes:

1. New database Package: I've introduced a new internal/database package to handle database operations. This package manages a single SQLite database connection that initializes on its first use and persists for the application's lifetime.
2. The SQLite database will be placed in the users OS appropriate directory in a typtea folder,
3. Stats Table: A new stats table is created within the SQLite database, storing each session's wpm, accuracy, and an added_at timestamp. While the timestamp isn't currently displayed, it's included for potential future features like historical graphs or detailed progress tracking.
4. Max Stats Calculation: The typing.go file now queries this database to retrieve and display the user's best WPM and best Accuracy directly on the results screen.
5. UI Integration: The view.go has been updated to show the new "Best WPM" and "Best Accuracy" alongside the current session's results.

There are a couple of issues that might be worth considering but I wanted to get feedback before making further changes, as they are a little more complex to integrate:

1. Is it valuable to store the language in the db as well? Should the Best WPM be for a specific language or across all languages?
2. Would it be useful to add a config where the user can configure if they see this information?

Thanks again for creating this! Let me know if you want any changes or if you would rather leave this feature for now.
