This adds the posibility of saving an SVG badge generated by the same shields.io dirictly to the gist. Instead of prepering a JSON file to be sent to their service, we use their library directly, which outputs an SVG file that we can save to the user’s gist. Filenames ending in `.svg` will use this library automatically. Additionally there is a major refactoring where the older `node:http` library has been swapped out for `fetch`. Also swap from node 16 to node 20 fixes #24

color-convert 
Color-convert is a color conversion library for JavaScript and node. It converts all ways between rgb, hsl, hsv, hwb, cmyk, and CSS keywords:
var converter = require("color-convert")();
converter.rgb(140, 200, 100).hsl() // [96, 48, 59]
converter.keyword("blue").rgb() // [0, 0, 255]
Install
npm install color-convert
API
Color-convert exports a converter object with getter/setter methods for each color space. It caches conversions:
var converter = require("color-convert")();
converter.rgb(140, 200, 100).hsl() // [96, 48, 59]
converter.rgb([140, 200, 100]) // args can be an array
Plain functions
Get direct conversion functions with no fancy objects:
require("color-convert").rgb2hsl([140, 200, 100]); // [96, 48, 59]
Unrounded
To get the unrounded conversion, append Raw to the function name:
convert.rgb2hslRaw([140, 200, 100]); // [95.99999999999999, 47.619047619047606, 58.82352941176471]
Hash
There's also a hash of the conversion functions keyed first by the "from" color space, then by the "to" color space:
convert["hsl"]["hsv"]([160, 0, 20]) == convert.hsl2hsv([160, 0, 20])
Other spaces
There are some conversions from rgb (sRGB) to XYZ and LAB too, available as rgb2xyz(), rgb2lab(), xyz2rgb(), and xyz2lab().
Contribute
Please fork, add conversions, figure out color profile stuff for XYZ, LAB, etc. This is meant to be a basic library that can be used by other libraries to wrap color calculations in some cool way.
