Description
### Steps to reproduce
1. Find a dataset with multiple measurements (see example file)
2. from qcodes.dataset.legacy_import import import_dat_file
3. data_621 = import_dat_file('mainfolder/data/621')
### Expected behaviour
Importing all of the data from, in this case, 621 to the SQL file.
### Actual behaviour
It imports all of the set points, and the first data array of measured data. It creates columns for the other measurements, but fills them in with NULL values instead of with the data.
### System
**Mac**
**QCoDeS/Qcodes**

Research direction
Start at qcodes.dataset.legacy_import and the import_dat_file entry point, then reproduce the issue with the example dataset at mainfolder/data/621. Trace how the set points and measured-data arrays are written to the SQL file; done means every measured-data column contains its imported values rather than NULL.
