unbalanced reading in some cdse jobs

[jdries]

Some jobs have 2 very slow reading tasks, that seem to read much more chunks compared to the others. This is weird.

It seems like this might be correct: the process graph looks like it tries to download 2 products covering a utm tile.
So it needs to retrieve all data for those tiles, and a few chunks for neighbouring ones.
The 'per product' reading strategy is a bit less optimal in this case.
