Feature Request; json status page

The home page of an imgproxy installation looks like this

I'd much prefer to see a json reponse saying that it was running, along with the version number, and really anything that's not secret.

Similarly, to me it seems odd that health would return so little, and in text.

I'm a big fan of imgProxy, but during the upgrade to version for, and eventually to Pro, I struggled with which version was installed.
