Move HTML resources to a new repository

[silverhack]

Is your feature request related to a problem? Please describe. Currentlly the HTML report also comes with a lot of external assets in the local filesystem, and once per report. For example, CSS files, JS files, images, etc are packaged alongside the single HTML file.

Describe the solution you'd like Instead to embded all the resources within the HTML, we can use the jsdelivr CDN service to serve assets and resources from Github repository. Having the icons, JS, CSS and fonts in a separate repository would help to create both, offline HTML and HTML reports that would fetch external resources such as icons, CSS and JS from cdn.

Additional context That change would help to reduce the size of the module and also would help to better monitor repository for potential updates, security issues, unused dependencies, etc..

Please, do let me know in comments if you have ideas about how to improve the HTML output.

Thanks,
