Support custom favicons

[choldgraf]

Proposal

I'd like to be able to set a custom favicon. Based on the website configuration docs I'd expect the configuration to look something like this:

# See docs at: https://mystmd.org/guide/frontmatter
version: 1
project:
  # title:
  # description:
site:
  template: book-theme
  # title:
  # options:
  #   logo: my_logo.png
       favicon: my_favicon.png

It will have to wait for the next mystmd release to work on github pages, but works locally now. ⭐

Should also work with svg and png.

@rowanc1 I think this may still not work on static html-generated sites...is that possible?

[rowanc1]

Yes! Not until the next release of mystmd (probably in a few days):

ohhh I see that's what you meant by "work on github pages"

Thanks for the new feature! I'm commenting just to tell you that in order for the new favicon to show up I had to delete the _build folder content. Maybe it's worth pointing this out somewhere in the docs?

Yes, we don't yet have a notification on the new templates being released. There is a note in the update instructions here:
https://mystmd.org/guide/quickstart

We are also tracking the issue here: #854.
