Decommission Bisq MailChimp account

[cbeams]

As documented in the comments starting at bisq-network/roles#27 (comment), MailChimp has shut down Bisq's account according to their new acceptable use policy which indiscriminately prohibits all cryptocurrency-related projects from using the MailChimp platform. On my request, they have re-enabled our account for a 48 hour period so that we can export our data.

We may reinstate this newsletter as a list under Bisq's own mailing list service at https://lists.bisq.network.

• Export subscriber lists
• Export newsletter template HTML (as developed in Redesign newsletter HTML/CSS #7)
• Back up email campaign archive
• Remove links to the MailChimp newsletter from bisq-network/bisq-website
• Archive this repository (in the GitHub sense of the word)

Closing as complete. Our email archive is now available at https://bisq-network.github.io/mailchimp. See also the README at https://github.com/bisq-network/mailchimp#readme.

I'm holding off on archiving this repository for now. I'm going to create an issue in bisq-network/lists about creating a bisq-announce list that we can be fully in control of (heads up @Emzy).

Then, next week, I think we can announce the fact that our MailChimp account has been shut down, and we can at the same time point people to the new list, so they have a call to action / something to do in response to the list being shut down.

One thing we'll need to decide is whether to import all the user emails from the old MailChimp list into the new bisq-announce list or not. It's about 3000 people.
