feat: New getFontInfo function

[alexmensch]

The purpose of adding this functionality is to allow download management of font files outside of the google-fonts-helper package. I want more control over when font files are fetched using caching so that font files aren't downloaded into my Eleventy dev project unnecessarily often.

Changes:

• Added new extractFontInfo method to Downloader class.
• Added getFontInfo function export to access method.
• Updated README with example

Here's an example of how I'm using this in an Eleventy project.

Global data file:

export default {
  css: async function () {
    return localCSS;
  },
  files: async function () {
    const fonts = [];

    for (const [url, fileName] of fontMaps) {
      const fontBuffer = await EleventyFetch(url, {
        duration: "1w",
        type: "buffer",
      });
      fonts.push({fontBuffer, fileName});
    }
    return fonts;
  },
  buildFontPath: buildFontPath,
  buildCSS: buildCSS,
};

.eleventy.js config:

// Write configured Google Fonts to build output
  eleventyConfig.on("eleventy.after",
    async () => {
      const fontBuffers = await fonts.files();

      for (const { fontBuffer, fileName } of fontBuffers) {
        const outputPath = path.join('_site', fonts.buildFontPath, fileName);
        const outputDir = path.dirname(outputPath);
        
        await fs.mkdir(outputDir, { recursive: true });
        await fs.writeFile(outputPath, fontBuffer);
      }
    }
  );

Hi @alexmensch
Thanks for the PR
It's a very specific case, we can improve the Downloader class to be able to meet this case.
I'll make some changes to the PR

Amazing, thank you very much for the consideration! I know it will make a big impact as 11ty has a huge usage base, and you've built a really nice library.
