feat(style): add conversions from the palette crate colors

[joshka]

This is behind the "palette" feature flag.

use palette::{LinSrgb, Srgb};
use ratatui::style::Color;

let color = Color::from(Srgb::new(1.0f32, 0.0, 0.0));
let color = Color::from(LinSrgb::new(1.0f32, 0.0, 0.0));

Given that the terminals are reexported, should this be reexported too (when the feature flag is given)?

There's no public code to export - just trait impls.

Srgb for example? Currently, this feature needs to be enabled and palette be added as dependency to your crate to use it?

Ah, gotcha. I'd expect that the only people wanting to turn this on are probably people that are specifically using palette already. Also we have a palette module already (so this could easily cause confusion).

I think I saw someone using palette colors in one of the videos before. So this will definitely be useful!
