Binder takes forever to setup

Hi all,

So I've had a few issues with binder. Would it be possible to hook in a github action which would generate the env for binder (sorry, I'm not 100% sure on how it really works).

Binder spins up a new image if the content in the repo is changed, so hooking it into a github action is a great idea. In my binder repo continuous deployment there is an example of testing the launch of an image from python, perhaps we can adapt that.
