Improve colour scaling of layers

[p-a-s-c-a-l]

please change the color coding of population. Green is completely misleading. If possible, put higher density above lower density in the legend. Color coding for population should IMO be similar to color coding used by Urban atalas for urban permeation and similar. red/brown, not green. I see that Mattia has some tresholds for population too. Maybe you can use these tresholds also for color coding the map.

In addition, it seems that the style for HW_DISCOMFORT_LEVEL needs to be adjusted. See clarity-h2020/csis#154 (comment).

Population so OK?

[DenoBeno]

Definitely better that green. Need to see how it look on a map.

I found an error.
Is it now ok?

[DenoBeno]

I look online and found that there are three layers showing population now. Red one look better IMO, but it's good to have a choice. I think that we can lave it at that now.

Here they are

I looked at discomfort levels map in Linz again, looks correct now.

For historical /yearly events, it's quite colorful now.

By the way, I believe that using the north European scales in Vienna and Linz is misleading. Especially Vienna has warm continental summers.
