JOSS paper on v3

[kartographer]

Description

As mentioned on a few telecons, now that we finally got v3 out the door, I'd like to get a brief updated JOSS paper out about the new version.

I pulled the author list from the updated maintainers an authors list, putting maintainers + authors first and then authors only second. Obviously this is a first pass (and as such, institutions, names, OCRID IDs will need to get confirmed).

Comments welcome! I kept the update relatively short -- I thought about adding a section on major changes since v2, but decided against it for the moment (though I'd happy to discuss that or any other additions).
