Reading modelDescription (during loadFMU) fails when array variables are used.

[juguma]

None of the attached fmi3-modelDescriptions can be read (fmi3LoadModelDescription(mdpath)) due to problems with the start values of array-parameters.

Since the Dymola-modelDescriptions (subscript D) and SimulationX-modelDescriptions (subscript SX) end in different branches in parseModelVariables, I added two variants of both.
For the Dymola-parameters it seems the problem is that they are sometimes not Floats, but Integers, I guess there is a casting (plus warning!?) missing.

PS: @ThummeTo sorry for the confusion yesterday where we couldn't find the "Dimension". We looked into the wrong file. My bad. Sorry!

this throws a warning now in #132
but parsing is not supported yet.

However, implementing arrays/vectors/tensors requires additional changes to FMICore. We should do that as part of a dedicated issue (feature request).
