Tab by target and then forecast date in reports

[seabbs]

At the moment the reports are tabbed by forecast date and then target. This can be quite annoying if you are comparing death forecasts across time as you constantly have to change the tab. A simple solution would be to reverse the tab order but this may not be ideal for people wanting to look at cases and deaths forecasts for a certain date. That isn't how I use the reports but maybe it is how some people do.

Another option is a different organization of the forecasts entirely but I am not clear what that is.
