Add support for centered, overlay text

[ejstembler]

Describe the problem

I'm using the multi and it works great. However, I'm wondering if it would be possible to add support for centered, overlay text? For example, I have a pipeline with many steps, however, some of them can be skipped and I'd like to denote that in the progress. Something like this:

# ┌ main  [■■■■■■■■■■■■■□□□□□□□□□□] 50%
# ├── one [■■■■■■■■Skipped■■■■■■■■] 100%
# └── two [■■■■■■■■■■■■□□□□□□□□□□□] 50%

How would the new feature work?

If this capability doesn't already exist, there would need to be a new method which performs the action with the text input. Something like:

progress_bar_download.overlay('Skipped', align: :center)

Drawbacks

This may be too tedious to implement.
