Can you add more archive websites?

As a previously mentioned on issue #55 archive.is was down for 3 weeks once.

I am wondering if you plan to add more archives in the future. Archive.org has been subject to having archives deleted in the past by bad actors with enough money. And archive websites could with time fall or be left abandoned (Such as webcitation.org, they say they are not accepting more archives). I believe the more sites are available in the extension the better, that way people can make sure their archive is not going to be lost, and people are able to choose an archive that they like more and is more suitable for them.

That shouldn't be too hard if I see this file:
https://github.com/rahiel/archiveror/blob/e62a69b5ea4de91fa26abec00cf1a80ef0c80382/src/archiveror.js

By adapting and adding a new function similar to archive_is and archive_org. For this we first would need the URL and query format/API specifications of the sites you would want to use.
