WIP: feat(position): Add function to place an overlay

[buztard]

This is just a quick POC I made the other day. Needs cleanup, proper testing, relative placement using lipgloss.Position and the ability to place the overlay outside of the background box, but so far it works as expected.

Addresses #65 and charmbracelet/bubbletea#79

This is quite neat and useful. Are you @buztard working on improving this for merging?

[mrusme]

What would need to be improved here for this to become mergable? @muesli @meowgorithm It would be super useful to have this for the time being until an actual compositor becomes available.

Ooo.

Hey, Marius! If this is something you need immediately I'd suggest simply moving the code here to a separate repo (or adding directly to your project). It's just string manipulation in the end and should be pretty straightforward.

Otherwise, we're could potentially merge this after vetting performance a bit and, more importantly, making sure it works properly with double-width runes (which I'm sure you can appreciate).

Hey Christian! Did exactly that, works like a Charm! Had to copypasta a few internals though, but it's okay for now. Would nevertheless be cool to have it officially available. :-)

Noted! In the meantime, @mrusme, I'd love to hear if you encounter any problems with the implementation (or if everything is awesome).

@mrusme The overlay one is nifty. Any idea how to make it work with https://github.com/lrstanley/bubblezone markers? @meowgorithm Overlay code works great, but not using those bubblezone markers from what I can tell.

Edit: After further test, it seems that essentially markers won't work properly when using the Overlay functionality. I do zone.Mark and zone.Scan, and it works. As soon as I use the .PlaceOverlay function, those markers don't work properly anymore.

Is this functionality going to be merged into lipgloss? Or is it going to be tackled as part of the "larger initiative" mentioned here: charmbracelet/bubbletea#169 (comment)? @meowgorithm

I've been using this .PlaceOverlay functionality with bubblezone markers and it's been working fine for me.
