adding xml feeds (rss) and api endpoints for programmatic access and eventual automation

[vsoch]

This PR will add different ways to subscribe programatically to what is going on at US-RSE! We currently just have one main rss feed, and this will add the following new ones (note these links obviously aren't online yet but will be):

• rss feeds for different kinds of content
• equivalent json feeds for the same.

The rss feeds are intended to be subscribed to by an appropriate service, while the json API is more suitable for a client tool. The larger goal of this effort will be to make it easy to do automation of integrating with other organizations to get our content.

RSS (xml) Feeds:

For each RSS feed, we provide the latest 100 items.

• https://us-rse.org/feeds/events.xml: subscribe to all US-RSE events.
• https://us-rse.org/feed.xml: subscribe to posts on the US-RSE site
• https://us-rse.org/feeds/newsletters.xml: subscribe to a subset of newsletter posts
• https://us-rse.org/feeds/dei.xml: subscribe to DEI working group events

Json Feeds:

JSON feeds are not limited in number, and we can provide this until a single page is not reasonable to load.

• https://us-rse.org/api/events.json: json list of US-RSE events
• https://us-rse.org/api/posts.json: json list of US-RSE posts, all types
• https://us-rse.org/api/newsletters.json: json list of US-RSE newsletters
• https://us-rse.org/api/dei.json: json list of dei events

In addition, I've added docs to the README, and since some folks will want to find this on our site, I've added a working group page for the website and this content.

Safe to ignore these for now, because we haven't merged this yet! 😆

I left some very minor suggestions. I think it's fine to merge without them if there is a reason not to change the order on the xml/json lists.

On a related note. The website working group page probably needs some more work, but I have no problem with what you have for now.

okay - posts.json and feed.xml (our main feeds) are moved to the top in both places cf2b833
