Bugfix/ls24003783/array in ds inz

[dom-apuliasoft]

Description

Given a DataStructure $A containing an array field $B, if $B was also marked with empty INZ keyword the system tried to initialize $B with a real number, throwing a runtime error.

To avoid this issue I added a check on the definition being an array during the creation process.
