/**
 * @author Extended, bugfixed and ported to TypeScript by Ikaros Kappler.
 * @modified 2018-xx-xx Added a clone() function.
 * @modified 2018-xx-xx Allowing leading '#' in the makeHEX() function.
 * @modified 2018-11-28 Fixed the checkHEX() function to accept 000000.
 * @modified 2019-11-18 Added a generic parse(string) function that detects the format.
 * @modified 2020-01-09 Fixed a bug in the parse(string) function. Hex colors with only three elements were considered faulty.
 * @modified 2020-10-23 Ported to Typescript.
 * @modified 2021-02-08 Fixed a lot of es2015 compatibility issues.
 * @modified 2021-02-08 Added basic tsdoc/jsdoc comments.
 * @modified 2021-11-05 Fixing the regex to parse rgba-strings.
 * @modified 2021-11-05 Added return value `this` to all modifier functions (for chaining).
 * @modified 2021-11-07 Changed the behavior of `darken` and `lighten`: the passed value is handled relative now which makes values much easier predictable and makes the change feel more 'natural'.
 * @modified 2021-11-07 Did the same with `saturate` and `desaturate`.
 * @modified 2021-11-07 Did the same with the `fadein` and `fadeout` functions.
 * @modified 2021-11-07 Added setRed, setGreen, setBlue, setHue, setSaturation, setLiminance functions.
 * @modified 2022-05-11 Modified the `clone` function by just copying the numeric calues, not re-calculating the whole color.
 * @modified 2022-05-11 Fixed the `interpolate` function.
 * @modified 2023-01-23 Added `Color.set(Color)` function to set all values (r,g,b,h,s,l,a) simultanoeusly.
 * @modified 2024-03-10 Fixed some NaN type check for Typescript 5 compatibility.
 * @version 0.0.13
