support for fixest

[pachadotdev]

Hi
Is there a plan to add support for fixest? I can come up with a PR for that

If you'd be willing to submit a PR that would be WONDERFUL! The only thing that gives me pause is I had been talking with @JaySumners about a fairly major PR that would change some (most?) of the current underlying architecture. So I wonder if it might be worth waiting until we move in that direction.

@JaySumners would you mind weighing in here on your thoughts?

I'd you've already got the PR keyed up, go ahead and send it in. I'm a bit stuck on wrapping for the refactoring so it may be a couple of weeks before I send it in.

Thanks!! I'll wait for the refactoring and then I'll work on it
