When an ASCII dataset (*.dat) contains status flags, Crayfish misinterprets the dataset #347

ASCII Datasets (.dat) can contain so-called "status flags" (look for istat in the [documentation](https://www.xmswiki.com/wiki/SMS:ASCII_Dataset_Files_.dat)). When these are present, Crayfish loads the dataset without complaining, but the displayed data clearly shows that the dateset has been misinterpreted.

When status flags are present, the dateset contains a status value (usually 1) for each node of the mesh before listing the actual data values.

Do you have an example file?

I sent you the link to a sample dataset by email

Data loading is done in MDAL for QGIS 3.4 release. Please reopen the ticket in the MDAL bug tracker with attached small (<3MB) example file.
