Update ux for openai to include space and color

[leerobertdyer]

This PR updates the openai script to add a simple background and spacing for the chat's response.

In regards to this issue

It
-Pipes the response through a sed command that replaces the "^" begin line character with "\t" a tab character
-Adds a simple background and text color to the response to make it stand out from remaining terminal text

NOTE
Is there a more convenient way to store reused variables like GRAY and RESET somewhere globally so we might not have to re-code them in different scripts? Or is it better to have them function in isolation?

Very interesting approach!

I mentioned in the the issue my preference for treating the output as clean plaintext so we can easily write pipelines that don't contain unexpected padding, etc. I think I'll stick to that for now.

But let's hold on to this, as it might come in handy for a --pretty flag or some other approach.

Thanks for considering this Lee!

Awesome yes I see how the prettier version could cause issues downstream with multiple pipes. Making it a flag is a great idea!

Is there a flag for this already or is this something I could potentially work on implementing?
