* Add license (#136)

Can't believe I forgot to do this from the start, heh. We need to make sure we have a license before we apply to https://sentry.io/for/open-source/

* Create FUNDING.yml (#135)

While looking for something unrelated I noticed that it was pretty easy to set up a "sponsor" button for this repo. I kept the original template in there in case we wanted to add things like the github usernames of individual core contributors (up to 4 allowed).
