Enhance favicon or add ability to override

[nathan-io]

Hello, thank you for this package!

I took at a look at the favicon tag, and it seems to be barebones.

I'm curious if it's possible to either exclude that tag (so we can define it ourselves), or, to enhance this package with broader favicon support across a variety devices and display sizes.

See this article goes in depth with some of the options and best practices.

As an example, the https://realfavicongenerator.net/ tool generates output like the following, depending on the user's chosen color settings:

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="manifest" href="/site.webmanifest">
<link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5">
<meta name="msapplication-TileColor" content="#da532c">
<meta name="theme-color" content="#ffffff">
