stylix: adding option for other wallpapers and improvements (DRAFT)

[no-mood]

I have adapted the function to generate a wallpaper with the Nix(OS) logo, taken from misterio77/nix-colors.

The code still needs some fixes, but the general idea should be there.

I thought of adding an additional file (nix-wallpaper.nix), which will be imported instead of the previous pixel.nix. This file will contain all the function calls that generate wallpapers based on a scheme, such as pixel-wallpaper and flake-wallpaper.

As I said, it still needs some fixes, and I haven’t changed the content of pixel-wallpaper.nix because it's not clear to me how to adapt it; in my humble opinion, we could follow the structure of flake-wallpaper.

Based on the patch, I am unsure what the purpose or functionality of this PR is. Could you clarify how it is trying to solve what problem?

Is it trying to resolve #242 or complement #477?

Actually, it's none of them if I understood correctly; it's more like a different wallpaper generator compared to the 'pixel' one. My idea is to extend the range of possible wallpapers generated from a color scheme.
Here is the wallpaper based on the color scheme I'm using.
EDIT: I'm gonna add a working commit soon

Actually, I am unfamiliar with the exact extent of the pixel function. @danth might be more helpful here.

The pixel function was not originally intended to generate a wallpaper, rather, it's a workaround for when we want a solid color but the application only accepts images.

It is currently only used in a single place within Stylix, in the GRUB module. (We could consider deprecating the pixel function and inlining it directly into the GRUB module instead?)

We should consider better renaming the pixel function and adding a comment clarifying its purpose.

What should we do about this PR then?

It might be better to keep the pixel function in the internal lib to prevent future code duplication: #327. Considering its current implementation is fairly isolated, it does not introduce any major code complexity.

Still, I think it would be a nice addition :)
If you're interested I can add a commit asap
