Feature: TabbedScrollableSelectPrompt

[ProjektGopher]

This PR includes all work to implement a new TabbedScrollableSelectPrompt.

If you'd like me to extract these into separate PRs, I can do that

The first three commits are structured such that they can be cherry-picked and merged as separate work beforehand. They involve the following changes:

• Adds support for ESCAPE, SHIFT_UP, and SHIFT_DOWN Keys.
• Adds the ability to specify the character to be used in DrawsBoxes::pad(), maintaining backwards compatibility by setting a default of ' '.
• Moves three methods for working with strings from the DrawsBoxes trait into another dedicated HandlesStrings trait which is then consumed by the DrawsTabs trait to avoid duplicate method name collisions.

The new DrawsTabs trait could then be merged on it's own. It's built in a similar way to the DrawsScrollbars trait. It can be used in any new prompts in the same way. This is the feature that ultimately enables the prompt in the example. It will also automatically scroll horizontally based on the selected tab in order to prevent overflowing and ruining the output.

Finally, the final 5 commits put all of this together to create our new component. I built this component because I wanted to include some readable context for the items from which I'm selecting. I'm thrilled with this solution, and I'd like to provide it for others to use as well.
