Add CI?
We currently don't have a CI for this repo. Should we? For the most part we've been depending in cmucl's CI to run with the ansi-tests, but maybe it would be useful to have a separate one for when we make changes here?
However, I'm not sure our current CI runners will work with this repo; I'll have to check to see if they're shared runners or not. If not, then I'm not going to try to set one up; it's sooo hard.
