Add support for .sci itervar parameter

[psoftware]

Since Omnet 5.2 version it's no more possible to import vector data generated by iterated experiments. The error is caused by a new .sci parameter type called "itervar" that causes the following error on loadDataset() call: Error in callLoadDataset: missing fields from block, file [...]

From the Omnet 5.2 changelog

Save iteration variables separately from run attributes ("itervar" lines). NOTE: This changes result file format!

This code should mantain the compatibility with the older .sci file versions.

Thanks a lot for the fix! It works for me. I hope it will get merged sooner or later...

I doubt (: If I remember well this package is based on the scavetool library, which has been modified in omnet 5.2. Some months ago I tried to merge the sources from the new library version, however I did not succeed because of some changes to class interfaces and my poor knowledge of omnet internals.

However this patch should help in the meantime, I'm glad it helped!
