Change tile width dynamically to allow longer strings

[BayMinimum]

Not really a priority, but this is going to happen as number grows beyond 8192 😢, since current implementation uses std::setw(4) when prining each tile.

I think this is a small bug and should be a quick fix if we work towards it!

As spotted, the game's UI is too binded with the game's logic. Currently working to separate the two.
(PR:#36 was the start of this to see if it would be accepted into the codebase).

You raised a good issue. Had I started development of the game with decoupled UI-logic in mind, it would have reduced the need for large code refactoring. #36 was a great start! I have added you (@cawvyoct) as a collaborator to this repository 😄

Although the UI and logic are locked together, we can reference the largestTile variable and expand the table accordingly, since it is calculated before the UI updates. Implemented in #56
