 * Parses a colour as OSC 10/11/12 and `xparsecolor` accept it.
 *
 * Terminals are inconsistent about how they answer a colour query: `rgb:` device specifications are
 * the documented form, but `#rrggbb` and bare X11 names both occur in the wild. Accepting all three
 * means a caller reading a reply does not have to guess which terminal it is talking to.
 * @param spec The colour specification.
 * @returns The colour, or `undefined` when `spec` is not a colour.
 * @example
 * ```typescript
 * import { parseColor } from "@visulima/ansi";
 *
 * parseColor("rgb:ffff/0000/0000"); // { b: 0, g: 0, r: 255 }
 * parseColor("#ff0000");            // { b: 0, g: 0, r: 255 }
 * parseColor("CornflowerBlue");     // { b: 237, g: 149, r: 100 }
 * ```
