Parameter Value[Data file content]" should appear at most 1 time(s)

Hi,
when validating with ISAcreator 1.7.9 an ISA created by `mzml2isa` (0.5.2) I am getting 
```
WARNING: The ISA-TAB field "Parameter Value[Data file content]" should appear at most 1 time(s) in current table
````
and indeed there are two columns, first about `MS1` and the second about `MSn` spectra. Which is correct from the mzML perspective. Will retry with v1.0.2 next. Yours, Steffen
