feat: virtual text overflow option

[LinkUpGames]

Currently, the virtual text will always be in the window's view even if the user horizontally scrolls past the virtual text's original position. I add an option overflow that prevents this and makes sure that the virtual text stays in place. I thought it would be nice to allow those that have nowrap set to off to only see the virtual text to where the symbol is at.

Thanks for the PR, it's a good suggestion!
