feature: Favicon

Is your feature request related to a problem? Please describe. Since most users prefer dark themes in their browsers they might have some dark readers/Themes for their Chrome, this resolves the problem with favicons having white backgrounds, which can be disturbing.

This is a good feature as it even does not interrupt the users who do not have any dark reader and helps the people with dark reader/Theme.

Describe the solution you'd like Remove the white background in favicon

Describe alternatives you've considered removing it helps to extract the white part and just keeps @hkirat 's image.
