Wrong "dataType" for integer variables

[letmaik]

I have a variable of byte type which pycovjson outputs as "dataType": "float" in the ranges part, this should be "dataType": "integer".

Which file are you using for this? @letmaik

It's the land cover one, but in general any file which has categorical data. So, this would also be relevant if you have a file that has a continuous temperature variable and then a categorical quality flag variable. I know that categorical data is not supported currently, but at least fixing the dataType shouldn't be too hard.
