solves #511

[lars-petter-hauge]

when the data is downloaded we also include all components that don't have a value. We should remove them and only include the ones with a number.

technically we would like to only show the ones where at least one row has a value greater than 0, with the special case that we want to show output columns even with all 0, with the input column does have value greater than 0 (so if one starts with 10 ppm H2S, the 0 ppm H2S in the output has a meaning)
