allow using CSS style color specs in the config
This change also allows removing the dep on the palette crate, which I found to be difficult to use (API changed often, and relied on a lot of `.into` that was hard to follow and reconcile across upgrades). We already pulled in the csscolorparse crate as an indirect dep of colorgrad, so we can replace the color conversion we need for sixel with that crate while we're in here. refs: #1615
