Older demo added to the download archive

Written by Richard Heyes, on 6th February 2022

I realised recently that a demo that I showed a screenshot of on this blog, albeit some time ago, wasn't in the download archive. So I've remedied this and the new demo is called demos/bar-grouped-purple.html (it'll be in the next release). Here's a screenshot of it in case you're curious.
