Oh-my-posh3: [Feature request] Set background & foreground inline

Prerequisites

• [x] I have read and understand the CONTRIBUTING guide
• [x] I looked for duplicate issues before submitting this one

Description

This is not an issue, its a "nice to have" feature.
As we read in the color documentation we can set a foreground color in the segment for any specific text.
It will be nice to be able to set also the background, i think something like this

<#ff0000,#00ff00>Hello budy!

Where the first or the second can be the foreground and background.

It will be usefull in escenarios like that, in where we want to put a "label" for an specific path (but not for the rest)

Thank you for this awesome tool !!!

Let's see what can be done. I think it's possible, and the suggestion could even work in terms of interface.

I was looking for a way to do this, and the syntax suggestion inspired me to get it set up. Hope that's all right! I'm no expert with Go, so feel free to suggest changes/totally alter it as needed.

Existing themes with in-line colors shouldn't need to change anything, the suggested syntax only adds new options.

And now I can connect plain style segments to powerline segments without a blank space between!

Should be live! (or ASAP 😅)
