Consistent screen update frequency if any sensors disabled

[NathanBaulch]

I noticed that if any of the sensor flags are disabled then the screen no longer displays each stat page for the same period. I've fixed this by introducing a loop so it can fall back to the next sensor type if one or more are disabled.

Also, thanks for sharing your Prometheus support here, works great!

Bump!

I have no issues with this, just don't have the time to drop it on one of my boards right now. If someone else could confirm no issues, I'd be happy to merge!
