Simplify Hydrogen mekko

[kaskranenburgQ]

Context

At the moment the Hydrogen mekko "Hydrogen supply and demand" has 40 series.
In more complex hydrogen scenarios it can become very hard to read to interpet this chart.
For example: This is the hydrogen mekko for the NBNL scenario Koersvaste Middenweg.

Current shortcoming

The chart is very hard to read due to the large amount of series inside.

Proposed enhancement

Redesign the hydrogen categories in the mekko.

Assigning @mabijkerk for now, re-assign at will.

Good suggestion! I think we have to realise that such a level of detail does not hold up in a chart if there are many series. We should have a simpler chart and perhaps capture the detailed information in a data-export or in a table.
