improve the "cluster to array" primitive

[TiTou]

When a cluster contains refs to different type of controls that have a common ancester, the "cluster top array" primitive should be able to handle it instead of having a broken wire.

Indeed, if the lower snippet works, one can assume that it shouldn't be too hard to get the upper one to work as well when possible.

by the way there is a discussion on LAVA about that, where I also describe my use case.

For the record, this already works for LabVIEW classes, so the code support for refnums with hierarchy should exist already.

Already in LV:

you don't need refs to meet this problem... even a cluster containing a I32 and a DBL can't be directly converted to a DBL array. kudos
